Sure would be nice if baseball current event-y stuff happened to fuel these, but I guess the World Series has to end before that. Anyway, see the title. I’m not asking about the best logo, just the worst. Nor is it limited to baseball.
Once upon a time, there was a website called LogoServer, which was amazing, because it had all sorts of logos for pretty much any league that bothered to have teams with their own logos (or even not their own logos). That website is no longer around. So it’s hard to give you reference material to pore through to find the absolute worst. You’ll just have to rely on your memory.
