Stately granite walls rise behind a manicured lawn of deep emerald, early-model automobiles parked in the curved drive giving the only hint that this serene campus near Denver once housed hundreds of tuberculosis patients seeking Colorado's famous healing altitude.

Mailed in May 1933 from St. Clair Shores, Michigan, the writer — a man named H.V. — sends a warm, practical note to a woman named "Mrs. Wm. Stringer" at 601 14th St., Port Huron, Michigan: "Will attend a Men's Club Rally in Port Huron on Sunday. Will bring the family along. If it is all right, we will come over to your house for supper. Will drop the family off earlier in the afternoon." A casual Sunday supper invitation turned into a time capsule of Depression-era Midwestern family life.
