An early demo recorded by Kiss guitarist Ace Frehley is being offered on eBay, with bidding at $3,550.
The sale will close later today.
The three song acetate demo was recorded in 1971 and features Frehley playing guitar in psych rock band Molimo.
It was discovered by a record collector in upstate New York, who told the Village Voice: "This guy had a barn full of 20,000 records.
"I went up there every Tuesday for a month and in the last shelf was a corner full of test presses and acetates. It was in there. At the time I had no clue what it was - I just bought them all.
"The cool thing about it is you can tell it's Ace playing guitar."
