Measures approx 12″ x12″ round. Slight Embossed Harley enamel emblem. Slight dome / globe shape. Looks great, more interesting than a newer one good for garage man cave office bar workshop etc. The back is also a little rusty. I’m not sure of the age, it is definitely enamel / porcelain. Good condition with rust and some wear and tare here and there especially near the mounting holes. Ask any additional questions. Please study the pictures as they are part of the description. Please see my other listings for sale. Heavy gauge steel domed globe style not flat.
