Cheap eBay find; fixed it for John Voss's Fuselage Codes site. A-26 at Keesler AAF marked K500:

Caption on back says "
B-26 parked at far end of field" so most likely 1948 or so; note the covers on the tires and taped-up intakes plus the little notes taped to the props. Name on the nose looks like
May or
Mary.
