A submarine glides beneath steel bridges in this layered geometric composition celebrating Groton's maritime heritage. Warm oranges and yellows glow above the water's surface while cool teals and greens anchor the depths below, creating a bold Art Deco style tribute to industrial Americana. Printed on smooth white card stock and made to order, artwork on the front, blank inside, envelopes included in every set. A handwritten note that arrives as an independent artist's work.
