Jefferson Machamer sure cranked out a lot of cartoons for these mags. He'd been quite successful in the 20s and 30s (he'd been cartooning since the 1910s) but his career was winding down at this point. Machamer died in 1960 at age 59.
It's interesting to see the selection of the "50 most provocative women." The only one I hadn't heard of is Rita Gam, She did a lot of film and TV work in the 50s and 60s and was also a documentary filmmaker.
By the way, I found this interesting comment on Jefferson Machamer: "Between 1935 and 1938 he starred in a series of 20 minute surreal comedies, produced by Al Christie's studio Educational Pictures Inc, the short comedy unit for 20th Century Fox."
