So M.C. Escher created a piece of art called "Smaller & Smaller". The problem is, when you look it up, two similar but non-identical pieces of art come up:
The color difference isn't a big deal, since Escher is known for making copies with different colors. The problem is the other, non-color differences (look at the corners in particular).
So, why are there two of them? Are both made by M.C. Escher, or is one a fake?
