Mr. A. Nielen’s Company of “Cin. O” manufactured what some collectors call real, real-photo postcards. Nielen cards aren’t the usual tourist views, they show real people and real scenic views. An extra reward for a Nielen card purchaser is on the back of most of his cards. There can usually be found a typed message vertically on the left side of an uplifting quote from a famous person or Mr. Nielen himself.
