Here’s one from the big blue folder, dated 12/05. 2-Strats explains a world of dingdongs. The same technique applied then as now: listen to other stoners talk, illustrate what they say.
Here’s an interview on Illustration Mundo with Trevor Grabill of Michigan.
Found this dude’s zine in a show at Gallery Anno Domini (in which we both had stuff). Wish I could say we had regular correspondence, but alas it isn’t so. His stuff is great! Make sure to also check out the excellent artists he names in the interview.
