Here's your chance to own a piece of Beatlemania. Two letters written before the Fab Four called it quits are about to go on sale. The pair of missives, written in January and April 1969, request then sever legal services for the band before they eventually broke up. The early letter, addressed to John Eastman, is signed by all four members plus record label head Neil Aspinall, while the second is signed by John, George, and Ringo. Moments in Time is hosting the sale, which expects to take in about $550,000 for both. Previously the April letter sold for $63,000 at Christie's in 2005. Do you have any Beatles artifacts? What do you own?
