1921 Beautiful photograph of the brand new "Einstein Tower" in Potsdam that was constructed by architect Erich Mendelsohn to prove the new and radical theories of Albert Einstein. This observatory still stands today but this was what it looked like when it was unveiled for operational use. Issued by Wide World Photos and stamped on the back, this presents well with a small rip on the far right side being the only real flaw.
