Sailboats stamps celebrate a favorite American outdoor activity with two colorful new postcard stamps. They feature abstract illustrations that capture the joyful sensation of being on the water on a beautiful day

Both stamps show boats cutting through the waves at full heel. The first depicts a single boat above royal blue waves, a white swell crashing against the prow. The white mainsail — adorned with a thick yellow stripe — and a pink jib stand majestically above a white, pink and gray hull, all set against a gray-blue cloudless sky.

The second stamp features two boats racing under full sail. The closer boat sports a teal-and-white mainsail and a pink jib — white spray curls from its white and teal hull. The farther boat has a sleek black hull and a white mainsail tipped with red.
