John Lennon Letter Up for Auction, Signed it the Day He Was Killed

Hours before John Lennon's murder he put pen to paper, for perhaps the final time in his life, and now that document is up for grabs ... to any collector with deep pockets.

The typed letter was personally signed by JL on December 8, 1980 -- the day he was shot and killed outside his NYC home -- and it's believed to be the last legal doc with his autograph.

John sent it to his accountant, Barry Nichols, and it lists 3 people to whom John gave his proxy to vote at an annual meeting for the Beatles corporations ... which was happening 9 days later in London.

This particular memorabilia is expected to fetch between $30k and $50k ... and if it does, that would be a sweet deal considering his last autograph sold for $100k!
