So, ya thought you'd seen all of the late-60s Marvel art by UK up-and-comer Barry Smith? Wrong! Here is a very interesting Captain America pin-up by Barry (years before adding the pretentious "Windsor" smack-dab in the middle of his modest moniker), created for a UK-only Marvel publication! Fun to examine today, as very soon, Smith's art would take on a modeled and detailed veneer, forever leaving behind this big, action-oriented (and somewhat clunky) Jack Kirby-inspired feel! BS would soon be making waves in comics fandom, first working on a few issues of AVENGERS and DAREDEVIL, then making his bones on the CONAN color Marvel comic! There was no mistaking Barry's youthful enthusiasm in those years, tho! Click to enlarge!
BONUS! Below (left): A panicked pin-up of Daredevil by Barry, done around the same time as the above Cap image! Below (right): A pic of BS himself, from the early 70s!
