The tapes contain a total of 27 songs and four-and-a-half hours of unedited, multi-camera professionally filmed concert footage with the original audio mix. The tapes also include intimate backstage scenes, candid dressing room footage and hallway shots of Elvis, his then-girlfriend Ginger Alden, and his father Vernon Presley.
"It was shot in Elvis' final tour for a one-hour CBS-TV special, 'Elvis in Concert'," Alana Nash, author of "The Colonel: The Extraordinary Story of Colonel Tom Parker and Elvis Presley", said of the videos.
"The special, which aired two months after Presley's death in August 1977, was immediately controversial, mostly for the ethics of shining the spotlight on a man so shaky and obviously ill, whose performances ranged wildly from embarrassing and sad to brilliant and triumphant," she continued.
The auction has stated that the videos are "not for reproduction, broadcast and/or publication."
Other Elvis' items at the auction include his 1972 Cadillac Custom Estate Wagon, 1958-1960 U.S. Army Induction and Discharge Papers, rare autographs from the late 1950s and early 1960s and photos of Presley on active duty in Germany and at play with the Memphis Mafia in Paris.
The auction will also feature a race truck owned by Steve McQueen, prescription sunglasses worn by John Lennon and the belongings of Roy Rogers, John Wayne, Marilyn Monroe, Burt Reynolds, Jimmy Stewart and Gene Kelly.
