Medicine Variety Book (1937).
[EPS ZIP (359k)] Medicine Variety Book (1937)
The clip art elements in the above file have been taken from a 1937 medicine "variety" book featuring "games, tricks, recipes, horoscopes," lots of customer testimonials ("Piles Made Him a Wreck") and level-headed product reviews: "Here's the AMAZING Beauty Cream That's Thrilling ALL America."
Oddly enough, since this book was originally copyright in 1937, the maximum number of years it could retain copyright is 67. This means that the first year of absolute Public Domain use is 2005. Happy New Year! I'm that eventually it will fall back into copyright given everything. I patiently await my takedown notice.
