75 paintings of currency and postage stamps by pop artist Robert Dowd (1936-1995), on loan from a private collector, are on display through mid-January 2013 at John Wayne Airport in Orange County, California.

You can see more images from the exhibit here.

From the airport notes about the exhibit:

Dowd became interested in art in 1957 when he was stationed at Camp Pendleton and came to Laguna Beach on liberty, encountering the artwork and paintings on view at the Laguna Beach art museum leaving him with an overwhelming desire to paint.
