A fleet of gleaming Fred Harvey motor coaches — long, dark, rakishly elegant — lines the rim at Mohave Point while a group of well-dressed 1930s tourists clusters beside them, dwarfed by one of the most spectacular vistas on earth: the Grand Canyon plunging away in layer after layer of ochre, rust, and shadow toward the silver thread of the Colorado River far below. These Harvey motor coach tours were the dominant way Americans experienced the canyon in the pre-war decades, and the vehicles shown — long-wheelbase touring coaches with roof racks — are historically datable to the mid-to-late 1930s. A message written in flowing cursive from a traveler named Jane, addressed to Marjorie in Washington D.C., bubbles with enthusiasm: "I've been riding around here today and have never seen a more beautiful spot. Mother and I are having a wonderful time. I wish my best friend didn't come with us. Weather fine and warm. Leave tonight for L.A." Postmarked Grand Canyon (partially legible, likely 1938–1940), franked with the ubiquitous 1¢ Washington green.
