Man-made Waterfalls - Boulder Dam
This card shows a picture of Boulder Dam, with a vintage car in the foreground. It says, Dwarfed by Boulder Dam itself -- yet these man-made waterfalls are higher than Niagara.
The back shows a map of main routes to Boulder Dam and Grand Canyon National Park. There is an article of three paragraphs about the new Boulder Dam and Lake Mead. It is put out by Standard Oil Company of California.
The surface of the picture was shiny, and now has crazing over it when you hold it to the light. The card is the size of a standard postcard.
