In 2002, Röyksopp pressed an ultra-limited edition of their double-LP Melody A.M with only 100 copies being made available to the public. They asked Banksy to spray-paint by hand all 100 of the copies and Banksy did. A copy sold in May for $6,962.
This may seem like a great deal since the last notably time someone tried to buy a piece of Banksy art, it self-destructed. I doubt this vinyl does that.
