Convex and Concave, lithograph, 1955.
“Next to each other are three houses with a cross vault as a roof. The left one is seen externally, the right one internally and the middle one optionally from inside or outside. There are several such inversions on this picture shown; one of them is described here. There are two boys playing the flute. One on the left looks down on the roof of the middle house; if he climbs through his window he can jump onto the roof below. If he then jumps down again, he ends up one floor lower on the dark floor in front of the house. However, the right flute player sees that same cross vault above his head as a roof before him there is no floor, but a fathomless abyss.” ~ M.C. Escher, Graphics and Drawings.
