This vintage advertising counter display features the trademark lion head of the Master Lock Company, which was founded in Milwaukee, Wisconsin. The piece is constructed from a cast composite or plaster material with a textured bronze-tone finish designed to simulate the appearance of aged metal. The sculptural bust depicts a snarling lion with a thick mane, gripping an advertising plaque in its teeth. The plaque bears the raised lettering MASTER in the center, with TRADE MARK in smaller letters along the bottom edge. This motif was adopted by the company in the 1920s to symbolize strength and security. The display is mounted on a solid rectangular wooden block base.
