Original 1952 meat packing trade magazine vintage ad for the TRANSPARENT PACKAGE COMPANY.  Main office and plant was located at 3520 South Morgan Street, Chicago, IL. Also located at 428 Washington Street, New York, NY and at 718 Terminal Bldg, in Toronto, Canada.  Look for this sign: WIENIE-PAK  and you'll find the casing that has revolutionized an industry. Frank and wienie casings.  ​This old one page magazine advertisement would display beautifully matted and framed.
