Mystery of Print Gallery Solved
In May 1956, M.C. Escher finished his lithograph "Print Gallery".
In a letter to his son Arthur he wrote about this lithograph:
"The odd print I told you about last time is finished, though not yet printed.
I don't think I have ever done anything as peculiar in my life.
Among other things, it shows a young man looking with interest at a print on the wall of an exhibition that features himself.
How can this be? Perhaps I am not far removed from Einstein's curved universe".
