Currently, there is a collection of Mark's work on exhibit, belonging to Mark and Margie Cromwell, and due to the positive response, it is still on display, but the museum is closed for the season.  It is in the historic deWitt Cottage Museum at 1113 Atlantic Avenue in Virginia Beach, Virginia. There are some photos of the show in the New Gallery section. Photographing the birds through glass was disappointing; they look much better in person.
