Edition of 1000 unnumbered, unsigned sets.

"These discs, turning at an approximate speed of 33 revolutions per minute, will give an impression of depth and the optical illusion should be more intense with one eye than two.

The 12 drawings will be best seen kept in their black frame, the larger ones throught the side of the frame.

In order to make use of the turnstile of the long playing record machines, see drawing showing how to place the pack of discs, above the pin, on white cardboard." - Marcel Duchamp
