The front and back of one of these wings are shown in [Figs. 6] and [6a] respectively.
It consists merely of a framework of wood, 11⁄2 feet long by 9 inches wide, over which a piece of white cardboard is nailed or glued. The desired scene is then executed on the cardboard in either oil paint, water color, or crayon.
The window itself should be cut completely out and hinged back again with a strip of linen, so that Punch and the other characters may poke their heads through ([Fig. 6a]).
The complete wings must then be hinged one on each side of the show, as seen in [Fig. 7]. In this diagram the wings are illustrated as seen from the inside.
