Ruddy granite boulders tumble toward the viewer in vivid linen color as a lone cog-railway car sits triumphant at 14,110 feet — the roof of Colorado — under a wash of peach and blue sky. This is Pikes Peak as tourists in the 1940s dreamed it: dramatic, wind-scoured, and impossibly high. The card was mailed from the summit post office itself on August 9, 1946, making it a genuine summit-postmarked piece. A sender named "Red" dashed off a breezy note to a colleague at McCormick Works on Chicago's west side: "Tem. 28° here! How is it there? Having nice trip. Regards to all the gang." The McCormick Works address — Bloomingdale & Western Ave, Chicago, Illinois — places the recipient squarely in the industrial heart of postwar Chicago. The summit station cancellation is sharp and collectible in its own right.
