I know a little about Ed Lepper. He was a prolific gag cartoonist whose work was in all the major markets. Just look at the notations on the originals from the editors: these cartoons appeared in National Enquirer, The Saturday Evening Post, The Wall Street Journal and other publications from the 1950s to the 70s.
If anyone has more information on Ed, please leave a comment here or contact me directly.
