This A5 postcard is perfect for bringing a smile to your friends' faces. If they carefully cut out the circles and glue the matching pairs together with a cocktail stick sandwiched between, they will be delighted by the magic image they see when they spin the stick between their palms (see film).
This postcard was inspired by the thaumatropes at Pollock's Toy Museum. There are instructions on the front and a message and address space on the back.
