Hand with Reflecting Sphere - M.C. Escher (1935)

Wander the gallery. Look at the art. Be polite. If you feel able please post some great art :)
From the reflection you can actually recreate what is behind the ball using this website.
That may work in real life, but this is a hand drawn image.
The levels of distortion around the edges of Eschers drawing don't match what is shown in your example.
