This slipmat is also a phenakistoscope, an early animation device that creates the illusion of a moving picture when a camera's shutter blurs its rotation.
This is a 12" slipmat print of this 45RPM design previously seen on a card.
To view the illusion, watch the spinning disc through your camera phone. Detailed viewing instructions here.
Full color print on 16oz white felt slipmats, printed in the USA by Glowtronics.
