CHATHAM – While the rest of Chatham concentrates on all the great and wonderful things about the town – and there are many – during its 300th anniversary celebration, the Art of Charity dares to go where no other organization has gone before: Chatham’s seamy underbelly. In a special tercentennial art auction and raffle, the Art of Charity Foundation shines the spotlight on the mooncussers and rumrunners who helped make Chatham what it is today but are seldom acknowledged for their contributions. On June 30, under a big top tent in Chase Park, the Art of Charity will take to the stage to honor this unacknowledged legacy while auctioning off art by some of Chatham’s best-known artists to raise money for local youth groups. Contributors confirmed to date include Marguerite Falconer, Ginny Nickerson, New Yorker cover artist Bob Staake, Jon Vaughan and Timothy Struna. Also on the block will be special one-of-a-kind Chatham packages, including a two-day stay in one of the remaining North Beach camps, a catered dinner for six in the elegant Eldredge Public Library, and golf at the exclusive Eastward Ho! Country Club. Add an extensive silent auction, a raffle of an “unburied” treasure chest filled with more than $2,500 worth of items from local merchants – from jewelry to tickets to Nantucket on Cape Air – some unannounced special guests, and the antics by hosts Otis Russell and Tim Wood (who together know all the seamy sides of Chatham) and you have the ingredients for an historic event that will out-historic any other in this very historic year! Admission to the event, which begins at 4 p.m., is free; there is a $10 bid registration fee. Food and drink – strictly legal, of course – will be available from the Pampered Palate. Previews of some of the art, plus more details about the auction and the Art of Charity Foundation, are available at www.artofcharity.com. The Art of Charity, a 501(c) 3 non-profit organization, began holding annual art auctions in 1994 and continued for 11 years, raising hundreds of thousands of dollars for the town’s youngsters. The auctions were retired six years ago, and fundraising continued through an annual appeal letter. This year the mooncussers who run the Foundation decided to resurrect the auction in honor of the town’s tercentennial and to once again highlight the need for continuing financial support for organizations such as Monomoy Community Services, boy and girl scouts, the Chatham Teachers Fund, the Eldredge Public Library and many more. Volunteers are always welcome, as are donations. For information, to donate or to volunteer, call 508-945-2382, or e-mail firstname.lastname@example.org.
