The image shows an old-fashioned biplane hanging from the ceiling in a museum. The biplane is yellow and blue in color with the number 2421 written on the side. It has a propeller and two propellers on either side of the fuselage. The propeller is black and appears to be made of metal. The body of the biplane has a curved shape and is painted in a light blue color. The background is dark, and there are several other biplanes visible in the background. The image is taken from a low angle, looking up at the aircraft.
