Two American flyers with A-26C Invader warplane (or B-26/RB-26). Seymour Mazer on the left.
The 491st began converting to the A-26 in late July 1945. However, the 491st planes would likely not have been all black (i.e., a night intruder aircraft) which typically was not done until Korea-era. Mazer would have been navigator, the other officer wears pilot's wings.
This may be the same model of aircraft that Lt. Mazer and two others were flying when they crashed in 1952.
