Standing like a sentinel at the foot of lower Seventeenth Street, Denver's ornate iron "Mizpah" Welcome Arch frames the grand clock tower of Union Depot beyond — a scene that defined the gateway to the Queen City of the Plains in the early 1900s, with horse-drawn vehicles, a bicycle messenger, and fashionably dressed pedestrians streaming past the Oxford Hotel awning in a city at the height of its Rocky Mountain prosperity. This colorized halftone postcard (No. 3067, published by the Great Western Post Card & Novelty Co., Denver, Colorado, catalogue no. A-5356) depicts one of Denver's most celebrated — and lamented — landmarks: the Mizpah Arch, erected in 1906 and demolished in 1931 to accommodate automobile traffic, making any period card featuring it a genuine historical document. The reverse is unused, undivided-back format with domestic 1¢ / foreign 2¢ stamp instructions, consistent with pre-1907 or early divided-back era production, suggesting a print date of approximately 1906–1910. The Hebrew word "Mizpah" (meaning "watchtower" or "may the Lord watch between us") was chosen to greet all arriving travelers with a blessing.
