Rock of Ages and American Falls, Niagara Falls
“This view taken below Niagara Falls shows the American Falls on the left and Bridal Veil on the right. Under the falls lies the Cave of the Winds, formed by thirty feet of projecting limestone. This so-called cave is 100 feet in height and 60 feet in depth.”
According to the back of the postcard, this is a Colourpicture Publication, Boston 15, Mass. Since the words “one cent” have been unceremoniously removed from the text “Place one cent stamp here” in the stamp box, we can surmise that the card was published no earlier than 1952.
