Nineteen Martha’s Vineyard artists> have been working outside this week, en plein air, to take full advantage of the exquisite September light and crowd-free vistas. The artists’ media range from oil and acrylic to pastel, watercolor and pen and ink. Each artist will exhibit views of Menemsha, the Edgartown Lighthouse and the Tisbury Waterworks as well as other favorite Island locations. The work will be exhibited concurrently at Dragonfly, Periwinkle and Pik-Nik galleries in Oak Bluffs. All Islanders are invited to stroll among the galleries during a reception on Saturday, Sept. 15, from 5 to 7 p.m. The exhibit closes Thursday, Sept. 20. Pictured above are artists painting by the Gay Head Lighthouse (from left to right) Susan Sellers, Kent Estabrook, Marjorie Mason, Thaw Malin and Monte Becker.
