Pacific 1997 Stamp Show
To commemorate the Pacific '97 Stamp Show in San Fransisco California, the USA issued a triangular pair — ~30 years after Rattlesnake Island Local Post issued it's first triangle stamp! The red stamp features a US mail stage coach topped with nine passengers; on the blue stamp a clipper ship is sailing by a cliff, on which there is a building flying the flag of the USA.
The Ship
The image on the blue stamp is based on a flyer for the ship Richard S. Ely.
