This image shows the Mt. Pleasant, Michigan Home and Training School, an institution for the developmentally disabled. Originally established in the late 19th century as a school for Native Americans, it closed in 1933 to reopen with its new purpose a year later.
There is no description on the back of this card.
The home was renamed the Mt. Pleasant Home and Training School in 1946, so the date of the postcard is most likely in the 1940s. The facility closed in 2008 due to budget shortfalls and declining attendance.
