Robert Crumb illustrates the Religious Experience of Philip K. Dick

The early 1980s were an exciting time for alternative comics. Shortly out of high school I discovered RAW, which was launched by the husband-and-wife team of Art Spiegelman and Françoise Mouly, and Weirdo, launched by the husband-and-wife team of Robert Crumb and Aline Kominsky-Crumb. It was in the pages of Weirdo that I discovered The Church of the SubGenius, Stanislav Szukalski, and a bunch of great cartoonists.

Crumb wrote and drew at least one story in each issue of Weirdo (which was published by Last Gasp from 1981 to 1993) and drew every cover. The covers are reminiscent of Humbug, a late-1950s humor magazine created by Crumb's mentor, Harvey Kurtzman (also the creator of MAD):

Some of Crumb's best work came out during his Weirdo period. In Weirdo #17, Crumb illustrated an 8-page story called "The Religious Experience of Philip K. Dick," based on a 1978 undelivered speech Dick wrote called "How to Build a Universe That Doesn't Fall Apart Two Days Later" and from passages in an out-of-print book called Philip K. Dick: The Last Testament.

Crumb's story focuses on Dick's bizarre hallucinatory experience of March 1974, in which Dick went back in time to the era of the apostolic Christians. Dick spent the rest of his life trying to figure out what these visions meant. Here's the first page:

Open Culture has an essay about Crumb's cartoon, and links to a low-res scan of the comic.
