This is the cover of Marvel Graphic Novel #6, Star Slammers, written and drawn by the legendary Walter Simonson, and published in 1983. This is one of the earliest American "graphic novels," which tended to run less than 100 pages and be printed in an oversized, 8 and 1/2" x 11" album format.
Star Slammers, a space opera epic about interstellar mercenaries, was a pet project of Simonson's dating back to before he was a comics professional. In the 90's he wrote & drew a 5-issue continuation, published by Malibu (& Dark Horse Comics). I don't have those issues, but maybe someday I'll track 'em down.
