This colorful wheel from 1931 features 40 Wonders of the World on the reverse.
This rather Art Deco wheel dates to 1932, when Myanmar, Thailand and Iran
were still Burma, Siam and Persia.
This 1933 nail gauge had a "loop" at the top so that it could be hung
in the nail section of a hardware store.
World War II saw a lot of these spotters, for airplanes, ships, insignia, etc.
This wheel looks decidedly Victorian, but it was actually designed for Holt, Rinehart & Winston by Aaron Heller in 1973. It's a spelling aid - the middle letter is stationary, while the beginning and ending letters revolve to form new words.
I enjoyed the book so much that I started rummaging through my own materials to see if I had a wheel, too. And here it is - my proportion wheel, which I still use occasionally for scaling items. I'll bet you've got a "volvelle" or two at your house.
Reinventing the Wheel is a most entertaining book, with wheels on everything from gestation periods for breeders, to presidential quizzes, to good old color wheels. And needless-to-say, it is richly graphic!
