Walk around the North Side of Chicago on a game day and you’ll see it everywhere. It’s on T-shirts. It’s tattooed on forearms. It’s flying from the porches of graystone two-flats in Lakeview. We're talking about the Chicago Cubs win flag, that simple, white banner with the royal blue "W" that has become a global shorthand for "we didn't mess it up today."
It’s kind of wild when you think about it. Most teams celebrate a victory with a social media graphic or maybe a siren. The Cubs? They turned a piece of laundry into a cultural phenomenon that borders on the religious.
But why?
The history isn't just about branding. It’s about a time before the internet, before television, and honestly, before people even knew the score of the game unless they were sitting in the bleachers.
The Low-Tech Genius of the Chicago Cubs Win Flag
Back in the late 1930s, the Cubs were owned by the Wrigley family—yes, the chewing gum moguls. Philip K. Wrigley was a guy who obsessed over the "fan experience" long before that was a buzzword in corporate boardrooms. He wanted a way to tell commuters on the elevated "L" trains whether the team had won or lost without them having to buy a newspaper the next morning.
Think about that for a second.
You’re riding home on the Red Line (or the equivalent back then), tired from work, and you look out toward the stadium. If you saw the white flag with the blue "W," you knew it was a good day. If you saw a blue flag with a white "L," well, you knew it was a typical Tuesday for most of the 20th century.
Wrigley actually experimented with the colors. In the very beginning, the colors were reversed. It’s weird to imagine now, but the win flag used to be blue with a white letter. They eventually flipped it because, frankly, the white flag stood out better against the Chicago sky. It was basically the original "push notification."

The 2016 Explosion
For decades, the flag was a niche thing. It was a Wrigley Field quirk. Then 2016 happened. When the Cubs finally broke the 108-year curse, the Chicago Cubs win flag didn't just represent a victory over the Cleveland Indians; it became a symbol of catharsis.
I remember seeing the footage of the clubhouse after Game 7. Players were draped in them. Fans in the streets of Wrigleyville were using them as capes. It transcended being a piece of stadium equipment and became a badge of survival. You weren't just a fan; you were a "W" bearer.
Sales of the flag went through the roof. Fanatics and MLB Shop couldn't keep them in stock. It became the most recognizable "non-logo" logo in professional sports. You can show that blue W to someone in Tokyo or London, and if they know anything about baseball, they know exactly what it means.
It's Not Just About the W
People forget about the "L" flag. It still exists, but the Cubs don't exactly sell a lot of merchandise featuring a giant "Loss" symbol. You won't see many "Fly the L" hashtags trending on X (formerly Twitter) unless it's a rival White Sox fan trolling the North Side.
The flag system is actually part of a larger tradition of flags at Wrigley Field. If you look at the masts atop the scoreboard, you'll see flags for every team in the division. Their height on the pole represents their current standing in the National League Central. It’s a physical, analog standings board.
In an era where everything is digital and fleeting, there’s something deeply satisfying about a guy climbing up a ladder to manually hoist a flag. It feels permanent. It feels earned.
Why It Matters for SEO and Brand Identity
From a marketing perspective—though P.K. Wrigley probably wouldn't have called it that—the flag is a masterclass in simplicity. It’s high contrast. It’s easy to replicate. It’s distinct.
Most teams have logos that are complex—think of the detailed bird of the St. Louis Cardinals or the intricate "NY" of the Yankees. The "W" is just a letter. But it’s a letter that carries the weight of a century of losing and a sudden, glorious moment of winning.
Honestly, the "Fly the W" campaign was probably the most successful marketing push in the history of the MLB. It gave the fans a job. It wasn't just "the team won." It was "we are flying the flag." It turned the act of being a fan into a verb.
Common Misconceptions About the Flag
A lot of people think the flag is a modern invention from the 80s or 90s. Nope. It’s been around since 1937.
Another weird myth is that it has something to do with maritime signaling. While flags are obviously a huge part of naval history, the Cubs flag doesn't correspond to any specific nautical letter that means "victory." It’s just a "W" for Win. Sometimes the simplest answer is the right one.
There's also the "Curse of the Billy Goat" connection. Some old-timers will tell you the flag was part of the bad juju, but that’s mostly just superstition talking. The flag has seen the worst of the Cubs and the absolute best.

How to Properly "Fly the W"
If you’re going to buy a Chicago Cubs win flag, there’s some unofficial etiquette you should probably know. You don't just leave it up all the time. That’s bush league.
- Only fly it after a win. This is the golden rule. If you leave it out after a loss, you’re confusing the neighbors and disrespecting the tradition.
- Take it down before the next game starts. The "W" is for the game that just happened. Once the next first pitch is thrown, the slate is clean.
- Don't let it get ragged. A grey, tattered "W" is a sad sight. If you’ve survived a Chicago winter, your flag probably hasn't. Replace it.
- Size matters. A flag that’s too small for your flagpole looks like an afterthought. Go big or go home.
The flag represents the pulse of the neighborhood. When you walk down Addison or Clark Street after a victory, seeing dozens of those flags catching the wind is a vibe you can't get anywhere else in sports.
The Future of the Tradition
Will the Cubs ever change it? Doubtful. The Ricketts family (the current owners) knows better than to mess with the few things that fans hold sacred. They’ve renovated the stadium, added giant video boards, and built a massive hotel across the street, but the flags remain.
Even as baseball moves toward more technology—pitch clocks, automated strike zones, advanced analytics—the Chicago Cubs win flag remains a stubborn relic of the past. And that’s exactly why it works. It links the kid in the bleachers today to the guy who watched Gabby Hartnett hit the "Homer in the Gloamin'" in 1938.
It’s a thread. A blue and white thread.

Actionable Steps for Cubs Fans
If you're looking to bring a piece of this history into your own life, here’s how to do it right:
- Verify the material: If you're buying a flag for outdoor use, look for heavy-duty nylon. Polyester fades in the sun and shreds in the Chicago wind.
- Check the dimensions: The standard "home" flag is usually 3x5 feet. Anything smaller looks like a boat flag; anything larger might require a commercial-grade pole.
- Mounting matters: Use rotating flag pole rings. There is nothing more frustrating than a "W" flag that gets tangled around the pole every five minutes.
- Respect the history: If you're at Wrigley, take a second to look at the top of the scoreboard after the final out. Watching that flag go up is the real signal that the day's work is done.
Whether the team is in first place or dragging along in the cellar, that flag represents hope. Every morning during the season, there's a chance that by 4:00 PM, a white flag with a blue "W" will be caught in the breeze over Waveland Avenue. That’s the beauty of baseball. There’s always another game, and there’s always another chance to fly the flag.
