An Atari 2600 (also known as VCS) cartridge with the game "E.T. the Extra-Terrestrial." This cartridge was excavated from the landfill at Alamagordo, New Mexico on April 26, 2014. Atari buried millions of cartridges in 1983 in order to remove inventory from their warehouse in El Paso, Texas. Due to scant and obscure written records as well as the coincidence of being buried near where Roswell occurred, the burial became in the public consciousness a urban legend, but the excavation revealed many cartridges which was then collected. The commercial flop of E.T. was one of the factors that led to a video game crash that started in 1982-1985.
A paper is attached to the game with a serial number from the City of Alamagordo as a certification that it came from the excavation. The serial number is COA / 08073.
