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!
As you know ... the Beatles legend was infamously murdered by Mark David Chapman as he was walking into The Dakota -- John and Yoko Ono's apartment building on Central Park.
Ironically, Lennon put his signature on something else that day ... a copy of his "Double Fantasy" album, which Chapman had asked him to sign hours before the shooting. That was auctioned back in 2020, and sold for $900k.
