A wooden board to which wooden strips are fixed lengthwise and crosswise. Both the strips and board are painted in such a way that three different figures will appear, depending on the viewer's position. If we stand in front of the board, we will see the image of the Virgin and Child; if we look at the board from the right, we will see the Virgin alone; if we look from the left, we will see a figure of a saint.
