BTW this is an example of the kind of thing you learn going to protests. Especially if you're in a big city, there will be people handing out materials and even booths for various antifascist groups.
Prior to this I was putting up paper flyers. Those weren't worthless, but many of them got taken down. The ones I put on derelict building stayed up the longest, but I figured just handing stuff to people probably spreads info better. Plus folks can have these in their wallets.
