Lake Koshkonong July 4 1937
According to the back of the photo it was taken at Lake Koshkonong on July 4, 1937.
This photo is part of a collection of 92 photos from an album found at an auction. I believe from obituaries and other items found in the album that the photos belonged to a family by the name of Shepardson from Beloit, Rock County, Wisconsin. I would like to return them to an interested family member.
