Mildly edited from a Loyola Marymount University website, “Sanitariums became popular in the late 19th century as hospitals to treat Tuberculosis … The Battle Creek Sanitarium in Michigan was operated by John Harvey Kellogg from 1876-1942, and promoted good health and fitness through diet, exercise, correct posture, fresh air, and proper rest.  Southern California’s mild climate made the area a particularly appealing destination for individuals suffering from respiratory ailments. The Long Beach Sanitarium advertised such courses of treatment as the milk diet and rest cure, and had electric and mechanical Swedish departments.”  The unused old postcard’s caption says nearly as much about this facility, and encourages you to “Mail this Souvenir to Your Friends.”  Indeed.  Grade: 1
