Bradley is wearing three stars. His date of rank is June 9, 1943, so it postdates that. My guess is the photo was taken during a War Department touring display to familiarize field forces with new gear. This tour occurred during February 1944 and traveled to Italyand Britain
. Lots of stuff brought along - down to the luminescent identification disks the 82AB and 101AB would wear on the back of their helmets in the Normandy jump.
If anyone knows where I could locate a hard copy of this photo (or a higher resolution electronic version), I would be pleased to hear of it.
