Eduardo Benito (1891-1981) was an icon of the Art Deco era. When I was young I enjoyed seeing his work while flipping through library copies of old issues of the Art Directors Annual, a publication that taught me more than any other about the history of commercial art from the late 1920s into the 1950s.
Here is the best biographical information I could find about Benito on the Internet. It seems that magazine publishing magnate Condé Nast kept Benito busy doing covers for Vanity Fair when he wasn't producing Vogue covers for him. Not a bad gig for an illustrator from Spain.
