Color image of "An Old Prospector on the desert, Southern Nevada," as written on the front of the postcard. Printed on the back of the postcard: "The old prospector and his burros are inseparably linked with the West's early history. These little fellows carry him over precipitous trails, where other transportation fails; he thrives and multiplies where other 'critters' starve, and whoever hears his musical bray echoing in the morning, appreciates the aptness of his sobriquet. 'Desert Nightingale.'"
