Hand With Reflecting Sphere

This lithograph printing by M.C. Escher, entitled Hand With Reflecting Sphere was created in 1935.  Here we can see that the hand holding the sphere is actually M.C. Escher's hand, which we can see in the reflection on the sphere.  In the sphere we can see one point perspective is used to depict himself and the rest of the room.  The reflection of the room is curved just as it would be due to the sphere.  This lithograph can also be considered as on of Escher's self portraits.
