Steranko provided Captain America variant covers for various Marvel titles throughout 2016-17 in recognition of Cap’s 75th anniversary. His Captain America #700 cover has a similar style to some of the anniversary covers (see “Preview: Marvel's Year-Long Run of Jim Steranko Variants”).
The variant from Lee features artwork of Captain America originally published in Uncanny X-Men #268. The piece has been recolored and polished for the Captain America #700 cover.
