I just put up a Facebook event , marked the address, and made sure I tagged what it was about clearly. FB did the rear

Understood! You could also do it like this… put a flyer up in coffee shops, comic shops, art supply stores. OR put out content on Insta or where you can tag the location of the town you’re in. Basically just to get the attention of where it’s likely an artist would be. Try it, it’s fun!
