c. 1940s-1950s; Trester Service Electric Co. – Milwaukee, Wisconsin Metal spring clip featuring bold black lithographed graphics for Trester Service Electric Co., a Milwaukee-based business specializing in electric motor sales, service, and repairs. The advertisement includes a detailed line drawing of an electric motor, the company’s address (235 E. Ogden Ave.), and their vintage phone exchange (BRoadway 1-1662). Promotional desk clips such as this one were widely distributed by service-oriented companies in the mid-20th century, intended to keep the business name in front of customers while serving a practical office or workshop function. The design reflects the industrial branding style of the era, emphasizing mechanical precision and reliability.
Clip shows moderate surface wear and some discoloration to the white enamel finish, consistent with use, but retains strong graphic detail and spring functionality.
