Gray Morrow (1934-2001) drew just about everything and worked for just about every comic book publisher who was around during his career. He drew Spiderman in the late 1960's and was well-known for his renditions of Zantanna for DC Comics. He also drew lots of newspaper strips such as Tarzan and Flash Gordon. Morrow also produced lots of covers and illustrations for science fiction digests. Below is a selection of his art:

Pekar was most famous for his autobiographical comic book American Splendor. He became more well known after his mid-1980's appearances on the David Letterman show. Then the 2003 movie exposed his work to an even wider audience.
I met Harvey at the San Diego comic con back in the mid to late 1980's. He was perfectly nice, he didn't seem to have a whole lot of patience but that was fine. He thrust a postcard promoting back issues of American Splendor into my hands and some photocopies of a New York Times review of the anthology. "Here, here, my publisher gives me this crap, I'm supposed to give it away I guess, take it."
I recently picked up a copy of the 1971 Comic Art Convention program. In addition to a transcript of Bill Everett and Joe Kubert being interviewed by Gil Kane and Neal Adams it contains a small portfolio with some good art (and some bad art). Below is the good art. Other guests at the convention included Jim Steranko, Gardner Fox, and James Warren.
