This is the best known of Escher's photographs. It's called 'The Bank Director at the Baths', 1938 (source).
It is a splendid photograph, of course. What would a Nazi think of it? 'One more bloated Jew.' Only guessing but I doubt I am far wrong and, so guessing, I consider the date and reflect that he has six years left. And so has my grandfather and all my mother's kith and kin. Less for them. As for my mother herself, within two years she will be working with the man who took this picture. And those below.
Many more photographs by Escher here, here (scroll down for two), here click on images), and here . No doubt more.
