Something like this doesn't exist in Poland, well not in the shape or form it's in the US. At most if someone has the ability to, you will see officially printed banners from a party being hanged on someone's fence.
Here's an example how this even looks like, straight from a banner printing service: https://www.taniebanery.com.pl/
Of course they are an eyesore, a waste of materials, and are littered fucking everywhere during election season.
Okay, sometimes there's exceptions
But they aren't novelty items that are stylized to look like straight out of Barbie.
So again. Why the fuck is America such a weird and wild country? Why the fuck would anyone promote a politician out of their own pocket in a "quirky" and "cutesy" or "relatable" way???
Jesus I hate the US. Yes this is a bit of a vent post, cry about it :3
Are bumper stickers a thing in Europe? Because that's where you'll find the real unhinged parts of Americana.
I've never seen one that's for a political party or something, but plenty for football clubs, "Polska Walcząca" with a child soldier drawing (yes we glorify those, look up Orlęta Lwowskie), maybe regional stickers, Calvin pissing, Apple stickers, Safe-Edgy type stuff.
Oh okay now I remember "***** ***" which stands for "Jebać PiS" (fuck PiS), but that's about it. Never seen something that would yell "Najsilniejszy wyborca Tuska" or similar to that.
AFD chuds do like bumper stickers. Some „hippie“ boomers do use political stickers as well.
