Caption: “Hoboken, New Jersey, circa 1905. ‘Holland America Piers with Manhattan across Hudson River.’”

At lower right are three men. Two are sitting on the steps of a building, the third man is standing holding something in his right hand, against his cheek and ear. His pose is the same as anyone today talking on a cell phone.
