The draft of Bob Dylan's Like a Rolling Stone, one of the most popular songs of all time, has sold for $2m at auction.
Sotheby's in New York said it was a record amount for a pop manuscript.
The draft is written in pencil in Dylan's own hand on four sheets of letterhead stationery from a Washington DC hotel.
It includes revisions, additions, notes and doodles of a hat, a bird and an animal with antlers.
The auction house said the seller was a fan from California who had bought the draft directly from Dylan.
The singer was 24 years old when he recorded the rock anthem - about an outcast debutante - in 1965.
The sale price topples the previous record for a pop manuscript - in 2010, John Lennon's handwritten lyrics for A Day in the Life, the final track on the Beatles' classic 1967 album Sgt Pepper's Lonely Hearts Club Band, sold for $1.2m.
