Here’s a Keith Haring letter with the same wording that’s also supposed to be from a 1992 Sotheby’s auction. The Lennon letter says “Stanley Park” while the Haring letter says “Brownling Green Park”.
No Thanks...The early days of rock'n'roll/Beatles auctions when lots of junk was mistaken for the real thing...if you look at the older catalogs...(late 80's-early 1990's)...it like a "Joe Long" festival...
