The Martha’s Vineyard Agricultural Society announced the opening of the annual Agricultural Fair poster contest, which will run through April 1, 2015. The 154th Agricultural Fair will take place from August 20 through August 23, 2015. Fair artwork should be submitted as a graphic design that will be used for the iconic Ag Fair posters and for reproduction on T-shirts, which will be available for purchase. Last year’s winning poster by artist Omar Rayyan depicted a portrait of Sonny Boy, a friend’s deceased horse, standing in a pasture, with a goose nearby. Submitted artwork must be sized to fit an 18-in. by 24-in. frame. Artwork should be sent to Martha’s Vineyard Agricultural Society, P.O. Box 73, West Tisbury, MA 02575. For specifications and questions, call 508-693-4343.
