French illustrator Raymond Brenot, aka Pierre-Laurent Brenot painted many magazine covers and pin-ups, and a few paperback fronts, as well. He also painted sleeves for numerous records. You see a beautiful example above for French trumpeter Fred Gérard's Si nous dansions... en 16 tours. The close-up image shows the unique aspect of the art—its mise en abîme element, or what the Dutch call a Droste effect, an identical image within the image, with infinite repetitions implied.

The title of the record translates to “If we danced... 16 turns,” which is weird because there are actually twenty songs. The tunes cover various dance styles, such as mambo, Charleston, foxtot, etc., and we know what you're thinking. You're thinking sixteen dance styles must be covered. No—only nine styles are played, so the 16 tours part of the title is a mystery to us. If you know the answer to the riddle, you know how to reach us. But don't expect an immediate response—we'll be busy foxtrotting.

Update: It is incredibly informative having readers from all over the world. The answer came from Jo B. in France, who informed us: "16 tours is the rotation speed of the record in 1 minute."
