A search of "Minnesota" revealed only two results, one of which was a picture of a battleship named Minnesota. The other was a picture identified as a guide at Little Norway in Blue Mounds, Wisc. It apparently made the Minnesota collection because "Minnesota farmer" was written on the transparency jacket.

Many of the color images document the late '30s and early '40s, a time when our parents and grandparents were changing American with their bare hands.
Unfortunately, we don't know who many of these people were, like this truck driver who helped building the TVA's Douglas dam.
