Original ice cream trade magazine vintage ad for C. NELSON MANUFACTURING COMPANY. Main office and factory was located at 4016 N. Union Blvd., St. Louis, MO. Manufacturers of automatic defrost merchandiser, model GFA-20, self service display unit. A sell-power shoppers can't resist. Confessed the best when put to test. This unique 1959 old dairy industry magazine advertisement would display wonderful matted and framed. Nice graphics.
