text: Farmingdale graphic artist Alan Claude's new poster, "Goat Island Clammers" debut Friday at the Yarmouth Clam Festival. The print features two iconic clam diggers with Goat Island Lighthouse in the background under a hazy blue sky. Claude has worked on his print for more than three years. The art is considered "Poster Style" reminiscent of the 1920's travel posters with its use of solid, bright and muted colors.
