Undated, but 1930s. Single sheet printed on both sides, folded to a 4 x 9-inch brochure, with bright color covers, b/w illustrations from photographs inside. Fine. Fritz Guenther began developing Murrieta’s natural hot springs as a resort in 1902, and his family ran it until the 1960s. This brochure describes the healthful properties of the springs (visitors were advised to drink the water as well as bathe in it, and in the “natural tule mud”) that promised to draw impurities from the system), the food, and the various levels of accommodation.
