Vintage portrait photo of Albert Einstein. This image probably dates to the late 1910s, when Einstein was director of the Kaiser Wilhelm Institute for Physics in Berlin. Six Brown Brothers credit stamps appear on the reverse, along with a Brown Brothers label and editorial markings. The photo (4x5.75") displays light-to-moderate creasing and is in Very Good condition overall. Culled from the legendary Brown Brothers Photo Archive. PSA encapsulated as Type III Authentic.
