Among the human depictions, "female images dominate and are nude, almost every one full-figured above and below," explained Guthrie, an emeritus professor in the Institute of Arctic Biology at the University of Alaska, Fairbanks.
Guthrie believes most of their creators were young men. He suggests it is not too difficult to theorize what was on their minds in their free time.
I recall an interview with Al Capp, the cartoonist who did Lil Abner many years ago. They asked him if he would ever draw a non-voluptuous woman and Al said:
"Not while I have a choice."
