Is it just me or do you see some similarities between these two images? The pulp magazine cover is from 1940. The Jimmy Olsen comic is dated 1961.
Yes, it is obvious, the Jimmy Olsen cover was derived directly from the July 1940 Thrilling Wonder Stories.
The editor for the Superman group of comics at DC was Mort Weisinger until his retirement in 1970. He had been active in early science fiction fandom from the late 1920's. He also was involved with an early sci-fi fanzine, Time Traveller, with fellow future DC editor Julius Schwartz and Famous Monsters of Filmland editor Forrest J. Ackerman. I am guessing the idea for the cover came from Weisinger, who would have been very familiar with the pulp magazines, and not from the artist, Curt Swan. I prefer the less static pose in the original pulp cover to the more upright Jimmy Olsen figure.
