The image shows a vintage US Marine Corps aircraft hanging from the ceiling in a museum. The aircraft is white with the number 21 on the side and the words "U.S. Marines" written on the fuselage. It has a red and black propeller and a green tail fin. The wings are folded down and the tail fin is pointed upwards. There is a sign on the wall behind the aircraft that reads "F4B-4". The aircraft appears to be in good condition with no visible damage or wear.
