Counterfeit Art

If you're not familiar with J. S. G. Boggs, this is his basic M.O.:

1. Create a one-sided drawing resembling paper money, but with different images, designs, and colors than the real thing.
   
2. Trade it at face value at a retail merchant, fully admitting that it is art and not legal cash.
   
3. Save the receipt and change, and sell it together online, with the name of the merchant they are from.
   
4. Watch collectors go nuts as they attempt to buy the original piece of art from the merchant, at far above face value.
   
5. See his art sell for 5 and 6 figures, framed together with the change and receipt that proves where it was spent.
   

I think it's brilliant, as a creative and social experiment. What's really wacky is the way he runs afoul of the Secret Service who think he is counterfeiting US currency. They just don't get it.
