Found: The Gem Room, Blue Mounds, WI

Little blonde girl wearing red coat and saddle shoes points to rock formations on this postcard promoting Cave of the Mounds. A performative photographic ploy to direct viewer attention in a vast dark space. Cave of the Mounds is often referred to as the "jewel box of America's major caves because of the variety, color and delicacy of its formations,"in tourist materials. The Cave was discovered on August 4, 1939 on a Wisconsin farm during a blasting session to mine limestone... eventually becoming a tourist attraction with spaces with names like Painted Waterfall, Gem Room, and Dream River Room. Hosting millions of visitors with a gift shop, hiking trails, and Prairie and Savanna Restoration Gardens, the land formation acts as spectacle like nearby Wisconsin Dells.
