a phony 1957 letter as a prank against self-claimed "alien contactee", George Adamski. After years of denying his involvement, evading the subject, and hinting at responsibility, Moseley admitted to the hoax in 1985. Adamski had become well known following publication of his 1953 book Flying Saucers Have Landed, and subsequent paraphernalia "evidence". Moseley published a damning exposé in Saucer News magazine. Just as word of Adamski's fakery was spreading, a letter of support came from an unlikely source. In 1957, Gray Barker acquired some blank U.S. Governmental official letterhead and envelopes from a friendwhite-seal, blue-embossed paper, with the American eagle watermark and the Seal of State impressed. During an evening "emboldened by the evil of alcohol", Moseley and Barker wrote seven prank letters using this official stationery. Five of the letters were jokes to friends, and two were outright hoaxes: the Adamski letter and one to Moseley's own father, which was never mailed, that "objected to his having indulged in extreme right-wing political activities while on a military pension, strongly implying he might lose the latter if he did not refrain from the former”. The letter to Adamski was signed by the fictional "R.E. Straith", a representative of the non-existent "Cultural Exchange Committee" of the U.S. State Department. Straith wrote that the government knew that Adamski had actually spoken to extraterrestrials in a California desert in 1952, and that the department also had its own evidence bearing out his claims. It encouraged him to continue his work of communicating his experiences to the public, since the government could not take an official position on the matter. Adamski took great pride in the Straith letter. He publicized its contents, and UFO proponents all over the world used it to validate their claims. When FBI agents investigated it, they informed Adamski that the Straith letter was a hoax and asked him to stop using it as evidence in support of his claims, but Adamski refused and he continued to display the letter in his lectures and talks. FBI agents also questioned Barker about the matter, but no criminal charges were filed. Many investigators tried to confirm or debunk the letter, without any categorical outcomes. Barker himself described it as "one of the great unsolved mysteries of the UFO field" in his 1967 Book of Adamski. As late as 1983, researchers Timothy Good and Lou Zinsstag concluded that "much of the evidence is
