Quirk Gallery on Broad Street has taken the unusual step of branding a line of merchandise to sell in its gift shop. Local artist Billie Wills has designed series of dinner plates with silhouettes of dogs. The series is limited only 250 plates with Boston terrier profiles have been printed so far but they are getting ready for a Chihuahua line and two more to follow. The melamine plates are not microwavable, but they are dishwasher-safe and come in a variety of colors. Quirk has also started selling its own greeting cards and T-shirts for doggies and humans.
