An interesting and uncommon instance of the new style of shaded relief that was capturing imaginations at the time. Issued the same year as Hal Shelton's similar work for Colorado, this gem by George W. Martin and Richard A. Pargeter shows this mountainous portion of Washington from North Bend and Darrington, east to Swauk Prairie and Lucerne. Richly detailed, it's amazingly legible and is dense with terrain and infrastructure.
Condition is very good. Image size is 23.5 x 30.5 (inches)
