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
It's such an odd thing for someone who comes from a country where your vote has been constructed as such a private matter that often members of the same family don't disclose their vote to others. I also found this to be very odd growing up, but came to understand it through the heightened stakes of class and a class war that isn't that far back in history that has over time been co-opted by the bourge "civilizing" mission of neutrality and being apolitical in your everyday life.
The vote then has become something protected that was dangerous to reveal in the past, that has lived on to this day, turning this into this unwritten social norm. It isn't proper to ask anyone who they voted for, much the same way salaries can't be discussed.
As a result nobody here would put signs like this anywhere where they could be associated with them. I'm not at all sure if this is better in any way from the US lawn signs, but it sure is different.
