Only one copy exists, found at a New York City stoop sale and bought with two other records for 75 cents. But its owner, Warren Hill, sold the record for $25,200 in 2006. The LP is an early version of Velvet Underground's debut album. Acting as the group's agent, pop artist Andy Warhol had assembled the acetate to shop to record labels. Tracks are in a different order than on the debut album, and "European Son" has more of a blues feel [sources: Rolling Stone and The Q Daily].
