Lot 17: Vintage Spratt's Dog Food Enamel Advertising Sign Builds Up A Dog

A single vintage advertising sign panel for Spratt’s Dog Food, identified through market consensus as an enamel sign. The panel features a white ground with the central graphic of the word SPRATT’S stylized in black lettering to form the silhouette of a dog. Below the main graphic, the slogan reads SPRATT’S ‘builds-up a dog!’ in a cursive script. The panel is bordered by a yellow trim. A portion of a blue panel is visible above the main sign, bearing the partial inscription UNTOUCHED BY HAND. The construction suggests enameled metal or tin, consistent with mid-20th-century advertising.
