Flight Instructor On Duty Metal Sign

Authentic reproduction airport sign. Porcelain enameled airplane signs have been said to be a true reflection of the times. Today, these aviation signs have become a collectible art form. This enameled airplane sign is an authentic reproduction utilizing the same process popularized in the early 1900's. The colors are not paint but finely ground glass crystals which, when kiln fired at 1350 degrees, fuse to the heavy steel plate. Each color is applied and fired seperately, creating a durable, lusturous and rust resistant final product.
