The late cartoonist Basil Wolverton is best known for his drawings of hideous-looking people: teeth with holes through them, blood vessels bulging out of foreheads, warts on warts, cavernous skin pores, tongues with grotesquely large taste buds, and so on. (One of Wolverton's claims to fame was winning an award given by Life magazine for the best drawing of Lena the Hyena, a character from Al Capp's L'il Abner, whose face was never shown in the strip.)
Here's a PDF file with several Powerhouse Pepper stories, a humor comic strip that Wolverton wrote and drew in the 1950s.
