SUNDAY FUNNIES - MAD #11, Basil Wolverton
The cover and this story was illustrated by guest artist Basil Wolverton(1909-1978). Basil become well known when he won a contest to submit the ugliest woman for an upcoming LL'L ANBER comic strip in 1946. Then with his Lena Hyena he proved he could draw grotesque beings. See Hyena's portrait immediately below.
Basil had two simi-big comic hits shortly after that. One was a space hero character like Buck Rogers and the second was Power House Pepper, which was sort of street kid with super powers.
