It's a cool experiment but not altogether surprising right? The provenance of a piece of artwork, and other rare goods, is arguably more important than the art itself. Especially in the case of artwork which is easily reproducible and copied.

If you think that's idiotic then ask yourself if you were given the opportunity to buy the first original Apple 1 or an exact replica, how much more would you be willing to pay over the replica? If the amount is greater than zero, then you're admitting that you're really buying an experience and set of emotional states in addition to a physical good.
