Pan American Airways Porcelain Sign: 18″ (dia.) x 2″ (deep) Small, vintage, heavy convex shaped enameled porcelain sign for Pan American Airways (has Dutch makers stamping on backside). This Co. was a 20th century cultural American icon and will be forever remembered for its style and innovations (operated from 1927-1991). A powerful and impressive piece, that is clean, bright and excellent, w/ nice rich surface patina (near mint), w/ exception of a few minor flea bites at outer edge. Note: We sold a larger 24″ (dia.) version of this sign last year for a hammer price of $4,500. Min. bid $100.
