Rising 175 feet above the impossibly blue mirror of Crater Lake, the Phantom Ship — a jagged volcanic island of andesite pinnacles and wind-bent conifers — dominates this dreamy linen-era postcard from Oregon's crown jewel national park, a solitary rowboat drifting at the island's base offering the only sense of scale in an otherwise otherworldly scene. Wesley Andrews, Portland's premier regional postcard photographer of the 1920s–1940s, shot this image and his company produced it using the C.T. Art-Colortone process — a registered linen-finish lithographic technique that gives the card its characteristic textile texture visible in the close-up detail image. The Phantom Ship, formed from volcanic flows estimated at 400,000 years old and among the oldest exposed rock in the Crater Lake caldera, was a perennial favourite subject for souvenir cards sold at park lodges throughout the Depression and WWII era. The reverse calls for a one-cent stamp, placing production firmly in the linen era before postage rose to 2¢ in 1952. Card number 875. Unused and clean — a lovely specimen of Pacific Northwest linen-era regional publishing.
