This beautiful First Day Cover features the New England Neptune (Neptunea lyrata), a large marine gastropod mollusk native to the cold waters off the New England coast and a member of the whelk family, known for its thick, ridged shell with a distinctive spiral shape. The 22¢ stamp (Scott #2118) illustrates a single, richly colored New England Neptune shell in pinkish-orange tones with detailed ridges and spire. The cachet artwork presents a delicate watercolor-style depiction: a large, open New England Neptune shell foregrounded against a soft ocean floor background, with two smaller companion shells below, all rendered in warm corals, creams, and subtle greens for a naturalistic, almost luminous effect signed by artist Tom Bjorn. Postmarked April 4, 1985 (issue date), in Boston, Massachusetts—with a crisp "First Day of Issue" cancellation (ZIP 02205)—this cover is ideal for seashell and malacology collectors, marine biology enthusiasts, New England regional philatelists, or those building sets on U.S. shell stamps. It remains in pristine unaddressed vintage condition with soft, painterly colors, clean composition, and no wear, perfect for display or nature-themed collections.
