Artists mined the stables of Walt Disney and Warner Brothers for comic inspiration:
"Porky Pig and the Grand Canyon Giant"
"Donald Duck and the Pixilated Parrot"
They adapted radio and tv series:
"Tom Corbett, Space Cadet"
Some of the early 1960s cartoons:
"Rocky and His Friends" (TV cartoon)
"Yogi Bear Joins the Marines" (predating Gomer Pyle)
"Yogi Bear Visits the U.N." (seriously?)
Some of the tv adaptions were head-scratchers, not at all popular with kids:
"77 Sunset Strip," about swinging bachelor detectives.
"I Love Lucy"
"The Life of Riley"
They adapted movies, some from years before:
"Francis the Talking Mule"
And comic strips, some from a generation before:
Some that I have never heard of:
Plus miscellaneous features:
"Smokey the Bear," about the advertising icon.
"Wrinkle Wrangle" (a song broken by the sharp crack of gunfire)
"Paul Revere's Ride" (history)
"The Lennon Sisters' Life Story" (1940s singing group)
"Yak Yak" (a sort of Mad Magazine)
"Brain Boy" (?)
One would expect a lot of beefcake, but in fact out of 1300 issues, I found 7 covers featuring beefcake photos:
2.-3. Two shirtless photos of Keith Larson as the Indian Brave Eagle, in a tv series that lasted for only 26 episodes (1955-56).
5. Kirk Douglas in Spartacus (1960).
At least two of the seven covers featured gay men, and a third had a gay subtext. Not a bad record.
