Vintage Heatwave Lighted Advertising Clock

This is a vintage Heatwave Heating and Air Conditioning electric advertising clock made by Southwest Manufacturing Company, with the Heatwave name and SM logo on the lighted panel and a dealer name on the lower edge. It is a lighted box clock with red spoke hands and a plastic face, powered by an old cord shown in the photos. The clock runs on line power and lights the panel; it has not been bench-tested for accurate timekeeping. The housing shows age wear, paint loss, and light rust as shown. Condition is fair to good and it displays well. Advertising clocks like this are collected for garage and shop decor. Estimated Value: $60 to $150 based on comparable recent sales. Sold as-is.
