Defiance Spark Plugs Double-Sided Flanged Sign
c. 1930s-1940s; Defiance Spark Plugs, Inc. - Toledo, OH
Double-sided flanged tin advertising sign for Defiance Spark Plugs, featuring the bold slogan "Predetermined Quality" above the company's signature plug illustration. The sign's deep orange background, contrasted with black and cream lettering, embodies classic prewar industrial design and early automotive branding. The flanged edge allowed for perpendicular mounting outside service stations and garages, giving roadside visibility to passing motorists.
Manufactured by Defiance Spark Plugs, Inc. of Toledo, Ohio, this brand was among the numerous midwestern spark plug producers competing in the early automotive aftermarket boom of the 1920s and 1930s. Their advertising emphasized durability and precision under the "Predetermined Quality" banner - a nod to the growing consumer demand for standardized engineering in the motor age.
This item shows signs of wear, especially parallel to the flanged portion, namely some large spots of rusting. However, the design remains vibrant. Please refer to photos for condition.
