The Troublemakers: From the Minnesota Farming Series
These pictures come from the Photos of West-Central Minnesota Farm Life, Early 20th Century set; they're out of order chronologically, and appear to be the various farming-families in their youth. From guessing at their ages and the car in the photo, I put the date at the late 1920s or early 1930s. I don't know what mischief they're off to get into...it probably won't be too serious, given the remote location of their farm, but I'm sure it'll be fun.
These last two don't appear to be congruous with the previous ones, but are probably from the same time period.
