Photograph of Mary Diack at an automatic book sewing machine for Braille, ca.1933. Standing left of a large piece of machinery bearing the name "Oversewing Co.", a woman in an apron slides a book through a metal section. The machinery is an elaborate metal piece, composed of wheels, mesh wiring and an assortment of intricate structures. Behind this, at right, sit stacks of paper, while a windowed wall lines the left.
