I just came across a comic by Art Spiegelman and Maurice Sendak. Here’s an excerpt:
The comic is a joint project with each artist drawing himself and some of the background (mostly by Sendak) and recording a conversation. This is a not uncommon method in underground comics — Crumb and Kominsky have done a lot of these. This particular comic appears on Francoise Mouly’s website Blown Covers which is often about the New Yorker where Mouly is art editor. Art Spiegelman is Mouly’s husband.
