We posted a similar series of these Hines photographs depicting child labor in Connecticut tobacco fields just the other day. If anything, these photographs seem to show a younger group of farm laborers at work.
This depicts a "second picking" of Connecticut tobacco.
While Hines was attempting to document child and teenage labor in an effort to address its abuses, scenes like this were not uncommon in American agriculture at the time. They would not have come to a surprise as the residents of Connecticut or anywhere in the East at the time.
Girls "stringing" tobacco.
