There are two pieces to this card. The coloured image is on the card at the back. In the front, pivoted at the centre, is a clear piece of plastic printed with a series of black lines. As this top piece is rotated the resulting moiré fringes give the appearance of movement. Made by BIZARR verlag and printed in Germany.
