This is a Memory Magic game with game piece cards and a plastic lenticular decoder. There are (32) two sided perforated cards with black squares. There are images in the black squares that can only be seen by putting the decoder over them. One side (pink) has animals, and the other side (blue) has different shapes. The game is played like concentration. There are two cards of each animal or shape and you make matches or pairs by remembering where another matching card is. There are game instructions on the back of one panel and the decoder is shown on another series number panel (pictured).
