Stop the Plant is a grassroots campaign to prevent the construction of a mammoth, 1,800-acre cement plant, pit and mine in New York’s scenic Hudson Valley. Area resident Woody Pirtle designed a poster that uses the plant’s monolithic 40-story stack as a powerful image of blight against the blue sky. The poster is being sold as a fund-raiser for the group, and the image has been adapted into storefront cards, lawn signs, benefit invites and other materials to rally support.
