Postcard, "Colorado Photography" by John Topolnicki. Captioned below the image: "In Quiet Remoteness - Mighty Pinnacles Reach For The Sky." On the reverse: "McCullough Gulch - Arapaho Nat'l Forest - South of Breckenridge, Colorado." and "From glaciers, from springs, from rivulets, these playful, crystal clear cascades, born from the heart of mountain peaks are in reality a sylvan setting, reflecting the myriad visions of serenity in our Colorado Rockies."
