Many readers have asked me "why do so many pulp covers feature women in ripped red blouses standing in swamps while a man fights off an unusual animal attack?"

Very little is known about Will Hulsey, but he worked on a number of men's pulp magazines in the 1950s and early 1960s including Man's Life, True Men, Guilty, Trapped and Peril. pic.twitter.com/LfE4xDaJjs

Sawyer's Photo Finishing Service began in 1919 in Portland, Oregon. By 1936 they had teamed up with William Gruber, who had been experimenting with stereoscope photography using the new Kodachrome colour film. pic.twitter.com/NaYkId36aT
