On Einstein's 72nd birthday on March 14, 1951, UPI photographer Arthur Sasse was trying to persuade him to smile for the camera, but having smiled for photographers many times that day, Einstein stuck out his tongue instead. This photograph became one of the most popular ever taken of Einstein, often used in merchandise depicting him in a lighthearted sense. On June 19, 2009, the original photograph was sold at auction for $74,324, a record for an Einstein picture.
