Boeing B-29 Superfortress “THUMPER”, of the 497th Bombardment Group.
It was the first B-29 to return home to the US after completing 40
missions, and went on a bond-selling tour.
The small Japanese flags denote claimed kills of Japanese aircraft
from the gunners (note the six on one mission - 27th January 1945 to
Tokyo).
The (even smaller) hearts next to the rabbits denote airmen wounded
aboard the aircraft on that mission.
