WASHINGTON — The U.S. Postal Service will celebrate the wonder of sharks by issuing the Sharks Forever stamps featuring five species that inhabit American waters — the mako, thresher, great white, hammerhead, and whale sharks. This issuance celebrates the wonder of sharks with a pane of 20 stamps featuring realistic images of five species that inhabit American waters: mako shark, represented here by a shortfin mako (Isurus oxyrinchus); thresher shark, here a pelagic thresher (Alopias pelagicus); great white shark (Carcharodon carcharias); whale shark (Rhincodon typus); and hammerhead shark, this one a scalloped hammerhead (Sphyrna lewini). Art director Derry Noyes designed the stamps pane with original artwork by Sam Weber. Forever stamps will always be equal in value to the current First-Class Mail one-ounce price.
