Although Steranko also did more work on the outside edge of comics that was more fan-oriented and small press, such as STERANKO'S HISTORY OF COMICS Volumes 1 and 2. With beautiful poster-worthy wraparound covers. (Announced as a six-volume project, he never got around to the other four. But I love the ones he produced.)
Steranko also created the fan magazine F.O.O.M. (Friends of Ol' Marvel) and did some very nice covers and pages for that series.
Steranko also did a lot of book covers, particularly a series of paperbacks reprinting The Shadow pulp stories.
And his COMICSCENE/MEDIASCENE/PREVUE magazine that ran from 1970-1994.
And some science fiction illustrations.
I especially like this illustration Steranko did for AMAZING STORIES in September 1969. Titled for publication as "Dogfight on 101", and later published under Ellison's selected title as "Along the Scenic Route" in Ellison's 1975 short story collection DEATHBIRD STORIES.
Poster-worthy, like the vast majority of Steranko's work.
