A baseball cap the writer Ernest Hemingway gave to his friend and biographer AE Hotchner has sold at RR Auction.
It realised $8,800 in the August 11 sale.
The two men met in 1948 and quickly became firm friends, regularly travelling together.
Hotchner explained in a letter of provenance: "In 1955 I was on Ernest Hemingway's boat, the Pilar, with him, when a heavy squall erupted and blew my cap into the sea.
"Ernest handed me his cap, and said he had another in the hold, and this was the cap he gave me.
"I wore it every time I went out on the Pilar with him."
