I agree about it not being about the money. The thing is with this sort of stuff, do you want her down the road buying it because it goes with her cushions and pay peanuts? or the guy up on the hill that agrees with the art and shows his appreciation. If this was not the case then we would all be able to buy rhino horn and ivory in the local cafe. Art should be an individual pieces with a price tag that is show in the quality and inspiration of the piece? To make it truly a one off maybe think about destruction of the code and drawings after each piece is finished? In terms of sets they should be made all at the same time and sold as individual pieces. For a collector that would make it all about the chase.

Rob who does the cartoons does not do them all the time. He sells them at the same place and has a small following. He is an artist and loves his work, it is not about the money just the satisfaction that others enjoy his work.
