Cost of art = the number of hours it took to produce x the hourly wage of the buyer.
Doesn’t work for everything, but I love the idea of meeting people where they’re at in this regard. Granted, if I’m making a living off of selling my work, and most of my friends are broke cartoonists, that’s going to take a lot of hustle to make ends meet, but it really makes the case for befriending people outside one’s own socioeconomic bracket. (And as a patron—especially one with a day job—it offers a great guideline for compensating people fairly. Got into this on Twitter a while ago and several people talked about tipping artists based on the knowledge that were probably almost always undercharging. I love those people.)
Anyway Mike’s auctioning off this gorgeous piece to benefit Ukraine. Good guy.
