Coca Cola Thermometer Sign Appraisal

Vintage Coca-Cola Contour Bottle Metal Thermometer Sign

This is a vintage advertising thermometer sign made of die-cut embossed tin or steel, shaped like the iconic Coca-Cola contour glass bottle. The sign features the classic red, white, and green color palette synonymous with mid-century Coca-Cola branding. The graphic depicts a full bottle with a crown cap at the top and the 'Coca-Cola' Spencerian script logo across the center, accompanied by the 'TRADE MARK REGISTERED' designation. A functional glass thermometer tube is recessed into a vertical slot toward the bottom of the piece, though the temperature scale markings appear significantly faded. Physically, the item shows substantial signs of age and patina suited for an authentic vintage piece, including surface oxidation (rusting) particularly along the edges and bottom, significant paint loss, and general scuffing throughout. There is a visible mounting hole at the top containing a white fastener. The overall aesthetic suggests a manufacturing date from the 1940s to the 1950s. The heavy wear and weathering indicate it was likely used in an outdoor or industrial environment, such as a general store porch or gas station. Despite the condition issues, the structural integrity of the metal seems intact, and the embossed 'Coca-Cola' lettering maintains good relief, which is a hallmark of quality for early lithographed metal signage.
