At right: a typical '60's page pencilled by Gil Kane, inked by Wally Wood. From the Noman story in Thunder Agents #5, June 1966. A pretty solid page even though the Kane pencils are somewhat obscured by Wood's inks.
From way back in 1957, the cover to Strange Adventures #83.
Kane was adept at drawing science fiction stories and Julie Schwartz didn't hesitate to use him. Here's a rather droll cover with George Washington and Honest Abe Lincoln enjoying some tunes. (Well, not really, but I don't know what Gil intended in giving them
earphones!)
