Boggs is an artist who draws paper money, but not for the sake
of counterfeiting (although the US Secret Service is not totally
convinced). Boggs' notes are very high quality and often include
subtle humor in their text and portraits. Because his subject matter
is paper money, Boggs has been very well received by the paper money
dealers (especially after having tables at some of the major paper
money shows). In addition to the art, Boggs is notorious for creating
thought provoking transactions with his art, offering it for
goods/services in lieu of real money. The people who accept this
transaction get the better end of the deal.
Boggs' real message is that money is an abstract concept that can
be manipulated in interesting and creative ways.
