This complete set of six airmail stamps commemorates the 50th anniversary of the Panama Canal's opening. Each stamp features a different vessel that transited the canal, including the SS Ancon, the first ship to officially pass through, and the nuclear-powered NS Savannah. The designs highlight the canal's importance to global maritime trade over its first half-century.

Issued in 1964, these stamps celebrate a major milestone for the U.S.-administered Canal Zone, a critical waterway connecting the Atlantic and Pacific oceans that revolutionized international shipping.
