Clear up your skin. Get popular. Dancing is pretty much the answer to everything. So you will want to know all about Arthur Murray’s Popularity Book (1944), which has recently been reprinted by Osprey/Oldhouse. The review’s over on Kitchen Retro - I can tell you, however, that not only will this book clear up your face, but if you want to get ahead at Uriah Q. Minkelmotter’s ice cream factory (and with a name like that, why wouldn’t you?), this book will show you how.
The ad above is from 1937 via Amazon.
(And many thanks to Old House/Osprey for sending me this - it was terrific!)
