Our Airplane Pilot on Duty porcelain enamel sign is an authentic reproduction of a Phillips 66 Aviation Products ad. Made in America, this novelty aviation sign features a United Air Lines Boeing 40 U.S. Mail aircraft. The steel sign is a great pilot gift or gift for a collector of aviation memorabilia.
The process to create this porcelain enamel Airplane Pilot on Duty sign is the same method used in the early 1900s. The colors are not paint, but are actually finely ground glass crystals. When the crystals have been fired at 1350° they fuse to the heavy 18 gauge steel plate creating this novel sign. Any slight markings or dings on the sign add to the vintage themed style.
