100 Forever Stamps 2019 USPS First-Class U.S. Postage Frogs Stamp 5 Books (20PCS/Book)

Some of the world’s most fascinating amphibians will hop into the nation’s Post Offices on Tuesday, July 9, 2019, when USPS releases its Frogs stamps.

Frogs live on every continent except Antarctica. There are approximately 4,800 different species of frogs, including more than 90 species that live in the United States.

Each stamp features one of four North American frogs:

The Pacific tree frog: Known for its familiar “rib-bit, rib-bit” call, this frog is nicknamed the “Hollywood frog” because it’s often featured in movies and television shows that call for nighttime scenes.

The northern leopard frog: This frog is known for its highly distinctive rattle-like snoring noise, followed by several “chuckling” or “clucking” sounds.

The American green tree frog: The rain frog or the cowbell frog is usually noisy after a warm rain.

The squirrel tree frog: Known for a raspy, quack-like call — much like the scolding noise of gray squirrels — this frog is found from southeastern Virginia through Florida and along the Gulf Coast to Texas.

William J. Gicker designed the stamps based on digital illustrations by Nancy Stahl, who used a palette of green and brown colors to capture the distinctive features of each frog.
