This sign was meant to demonstrate the effectiveness of Andrew Fryberg's 1896 patent in making revolvers safe to carry with a loaded chamber. The patent allowed for no direct contact between the hammer and the cartridge, what is today referred to as a transfer bar. The sign measures 15 3/4 inches wide and 11 3/4 inch tall, it is hung on a wrought iron shop sign style mount. Includes some additional information about the transfer bar patent.

Very fine, showing light wear on one side with mild wear and some areas of oxidation on the other. Overall vivid colors and sharp details.
