Photoshopped kids' versions of great works of art

Today on the Worth1000 photoshopping contest: classic works of art as executed by their creators as small children. My favorite is pictured here: MC Escher's "House of Stairs" as graded by a stroppy art teacher: WRONG WRONG WRONG!

Update: Bernardo sez, " The lovely Worth1000 Escher-inspired kid-style drawing
contains elements from Concave And Convex, Waterfall, and Belvedere,
not House of Stairs."
