A copy of the Beatles' White Album, signed by Charles Manson, is on the auction block at website iOffer.

Interested parties can skip the auction all together and purchase the item for $50,000.

The LP was said to be a major influence on the Manson cult, which committed a series of murders in L.A. in 1969.

"Manson believed that the Beatles spoke to him through their lyrics, especially those included in the White Album, released in December 1968," notes the site UKMC.edu.

"Several songs from the White Album crystalized Manson's thinking about a coming revolt by blacks against the white Establishment."

The autographed copy also contains the signatures of Manson family members Susan Atkins, Leslie Van Houten, Charles Watson, and Patricia Krenwinkel.
