You’ve seen the signs. Honestly, if you’ve spent more than twenty minutes wandering through the French Quarter or the Marigny, you’ve definitely seen them. Those ubiquitous, jagged wooden planks painted with a simple, frantic message: Be Nice or Leave. It’s the unofficial law of the land in Louisiana. That’s the magic of Dr Bob folk art. It isn't just decoration. It’s a vibe, a warning, and a piece of cultural history all hammered into a discarded piece of cypress siding.
Bob Shaffer—the man the world knows as Dr. Bob—didn't go to medical school. He’s a self-taught visionary. He’s been a central figure in the Outsider Art scene for decades, operating out of a sprawling, chaotic, and utterly fascinating studio on Chartres Street. People flock there. Not just for the paintings, but to breathe in the fumes of old tin, turpentine, and pure, unadulterated grit.
The Man Behind the Be Nice or Leave Legend
Dr. Bob grew up with a foot in two worlds. Part Cherokee and part "white guy," as he often puts it, he spent his formative years soaking up the textures of the Mississippi River and the back-alleys of New Orleans. This isn't polished gallery stuff. It’s raw.
He started out cleaning and repairing things. He was a tinkerer. That mechanical background is visible in the way he constructs his frames out of found objects—old roofing tin, bottle caps, and rusted nails. He treats "trash" like gold. In the early days, he was just another guy trying to make a living in a city that values character over currency. But then the phrase hit.
"Be Nice or Leave."
It started as a sign for a local bar. It wasn't meant to be a global brand. But New Orleans is a city of extremes; it’s a place of incredible hospitality and occasional, sudden chaos. The phrase resonated. It captured the local ethos: we’re having a good time, don't ruin it. Today, those four words are found on everything from massive $5,000 commissions to $20 magnets. But the authentic Dr Bob folk art pieces—the ones hand-painted on old barge board—those are the ones that collectors obsess over.
More Than Just a Slogan: The Swamp Blues Aesthetic
If you think he’s a one-trick pony with a catchy phrase, you haven't looked closely at the swamp. Dr. Bob’s work is a bestiary of the bayou. He paints alligators with jagged teeth that look like they could actually snap. He paints crabs, crawfish, and the "Swamp Blues" characters that populate his imagination.

The materials matter. A lot.
Most people don't realize that the "frames" on his work are often as important as the painting itself. He uses vintage ceiling tin. He beats it, folds it, and nails it down with a rhythmic precision. It creates a 3D effect. The metal is sharp. If you run your finger along the edge of a real Dr. Bob, you might get a scratch. That’s part of the deal. It’s art that bites back.
Why Outsider Art Captures the Imagination
Outsider art, or art brut, is created by people outside the traditional art establishment. No fancy degrees. No "theory." Dr. Bob is the poster child for this movement in the South. His work is visceral. It’s about the "push" of the paint. When you look at his thick, impasto application of house paint and industrial enamels, you can see the speed of the work. He doesn't overthink it.
- He uses found wood from demolished homes.
- The paint is often whatever was on hand—bright, garish, and durable.
- The themes are local: jazz musicians, hoodoo symbols, and the ever-present gator.
Collectors like Dan Aykroyd and various rock stars have bought in, but Dr. Bob remains accessible. You can walk into his shop and, if he's in the right mood, he'll tell you exactly what he thinks about the state of the world while he hammers away at a piece of tin. It’s performance art as much as it is visual art.
The Deep South Roots of the "Doctor"
How did he get the name? It wasn't a marketing ploy. In New Orleans, everyone has a nickname. He was the guy who could "fix" things—the doctor of junk. The name stuck.
Living in the Bywater neighborhood for years, he witnessed the transition of New Orleans from a gritty, industrial port to a gentrifying hub of creativity. His studio at 4173 Chartres St is a fortress of the old ways. It’s packed with hubcaps, animal skulls, and stacks of weathered wood. It’s a sensory overload.

There's a specific honesty in Dr Bob folk art that you don't find in the polished galleries of Royal Street. It’s "dirt road" art. It reflects the humidity, the decay, and the eventual rebirth that defines the Gulf Coast. When a hurricane hits, Bob is there picking up the pieces—literally. Much of his best material comes from the wreckage of the city.
Recognizing Authentic Dr. Bob Pieces
Because he is so popular, there are fakes. Tons of them.
How do you tell if it’s real? Look at the back. Dr. Bob pieces are heavy. They use real barge board or heavy cypress. The nails are specific—usually old-fashioned, square-head nails or heavy-duty tacks. The signature is usually bold, written in paint or Sharpie, often with the "Dr. Bob" logo that looks a bit like a prescription pad scribble.
The eyes of his animals are another giveaway. They have a frantic, wide-awake look. Whether it’s an owl or a catfish, there’s a sense of life behind the paint. It isn't "cute." It’s folk art with an edge.
The Market for Folk Art in 2026
The market has shifted. Ten years ago, you could grab a small "Be Nice" sign for fifty bucks. Now, prices have climbed as people realize that self-taught masters like Bob Shaffer won't be around forever. It’s an investment in a disappearing version of the American South.
- Small Signs: Usually $150 - $400 depending on the wood quality.
- Mid-size Animal Portraits: $800 - $2,500.
- Large Scale Tin Compositions: Can easily fetch $5,000+.
But don't buy it because you think it’ll triple in value. Buy it because it reminds you of a late night in a dive bar where the jukebox was playing Professor Longhair and the air felt like a warm wet blanket. That’s the real value.

Why the "Be Nice or Leave" Message Resonates Now
We live in a loud world. Everyone is yelling. In that context, a hand-painted sign that tells you to either be a decent human or hit the road feels revolutionary. It’s the ultimate New Orleans boundary. You are welcome here, regardless of who you are, as long as you bring good energy.
It’s a philosophy. Dr. Bob has mentioned in interviews that the sign was never meant to be mean-spirited. It was meant to protect the "good times." If you're at a party and someone starts a fight, they gotta go. Simple. That simplicity is why you see his work in kitchens in London, offices in New York, and porches in Tokyo.
Final Thoughts on Collecting the Swamp
Collecting Dr Bob folk art is about more than just owning a painting. It’s about owning a piece of the levee. It’s about the smell of the river and the sound of a hammer hitting tin at 7:00 AM in the Bywater.
If you're looking to start your collection, don't just buy online. If you can, make the pilgrimage. Go to the studio. See the "Bottle Cap" walls. Talk to the apprentices. The experience of buying a piece of Dr. Bob art in the place it was birthed is half the point. You'll leave with a heavy piece of wood and a better understanding of why New Orleans refuses to be like anywhere else.
Actionable Steps for New Collectors
- Visit the Studio: Go to 4173 Chartres St in New Orleans. It’s the only way to see the full scale of his work and the environment that inspires it.
- Check the Materials: Ensure the piece is on reclaimed wood. True Dr. Bob art uses "found" materials, not new plywood from a big-box store.
- Look for the Tin: The best pieces feature the hand-crimped roofing tin frames. This is a signature element that is difficult to replicate.
- Verify the Source: If buying secondary, ask for the provenance. Most original owners have a story about meeting Bob or buying it from a local Louisiana festival like Jazz Fest.
- Start Small: A "Be Nice or Leave" sign is the classic entry point. It’s the cornerstone of any Southern folk art collection.
Support the artist directly whenever possible. Folk art is a living tradition, and keeping the "Doctor" in business ensures that the weird, wonderful spirit of the swamp continues to have a voice. Be nice.
