One of the most popular songs of all time, Bob Dylan's Like A Rolling Stone, is going under the hammer in New York this summer.
Auction house Sotheby's is offering a working draft of the finished song in Dylan's own hand for an estimated 1 million to 2 million US dollars (£600,000 to £1.2 million).
The draft is written in pencil on four sheets of hotel stationery and contains revisions, additions, notes and doodles.
Scrawls seem to reflect the musician's experimentation with rhymes.
Dylan was only 24 when he recorded the song in 1965.
Sotheby's described the seller as a long-time fan from California who "bought directly from Dylan". He has not been identified.
The auction house said it is "the only known surviving draft of the final lyrics for this transformative rock anthem".
The sale is taking place on June 24.
