Majestic 12 / MJ-12 Crewneck Sweatshirt

Majestic 12, also known as MJ-12 for short, is a purported organization that appears in UFO conspiracy theories. The organization is claimed to be the code name of an alleged secret committee of scientists, military leaders, and government officials, formed in 1947 by an executive order by U.S. President Harry S. Truman to facilitate recovery and investigation of alien spacecraft. The concept originated in a series of supposedly leaked secret government documents first circulated by ufologists in 1984.
