On Jan. 28, USPS will release the new issue in panes of 20 stamps and coils of 100 stamps. Each stamp depicts an iconic seashell found in North American waters: the alphabet cone; the Pacific calico scallop; the zebra nerite; and the Queen conch, commonly known as the pink conch.
Art director Greg Breeding designed the stamps, and Sergio Baradat created the stamp art. The stylized design includes horizontal swaths of white and blue in the background, suggesting waves have washed the shells onto a beach.
The first-day postmark will read San Diego, Calif.
