It’s a Good Life If You Don’t Weaken, by Seth

Second frame of third chapter (set in the Royal Ontario Museum dinosaur gallery):

A classic graphic novel from the early 1990s, claiming to be autobiographical, about a Toronto comics artist who becomes fascinated with a Canadian cartoonist of the 1950s and 1960s, and goes on a voyage of discovery about both his predecessor and himself. I’m trying to identify who recommended this to me, or whether I just picked it up because I liked the title; I really enjoyed it, though I hope that the writer is a nicer person in real life than he comes across as being here.
