Gaza and the seat of Primghar anchor this mid-century survey of O’Brien County, where the agricultural grid is etched with family-named creeks and legacy institutions. The Illinois Central railroad cuts a diagonal path through the landscape, connecting the elevators of the small towns to the wider world. The map captures a transition in civic life, showing the County Home and County Fairground alongside the Primghar Airport, documenting how public infrastructure evolved in the post-war era.
