A photograph shows UFO "kill markings" on the side of a German World War II anti-aircraft gun.
A photograph purportedly showing “kill markings” that indicate flying saucers on the side of a German World War II anti-aircraft gun has been showing up on the internet for several years, often used as proof that unidentified flying objects are a part of the historical record:

The original photograph was lifted from the cover of a 1943 issue of Der Adler, a Nazi propaganda magazine:
The caption identified the kill markings on the weapon as 11 planes, 40 armored tanks, and 15 anti-aircraft forts. There was no mention of UFOs.
