from visiting a few anime and furry cons in my life, I wonder which is more difficult to make money from as a dealer. like if you're an artist, for example
it's easier to know what you should target when you're selling at an anime con, you aim for either very contemporary series or one's with diehard fanbases. for a furcon, outside of flavor-of-the-month characters, you're usually having to make something original that would appeal to a certain stylistic sensibility
commissions are almost nonexistent in the anime fandom because people there follow existing characters rather than making OC's. you have to deal with networking and all that junk, but it's a revenue stream somewhat unique to furry artists
context: I lived with a skeezy friend for a few years who operated a sizeable furry art print business. I helped out here and there, it was an odd product to try and sell sometimes
