Each has a bolt and nut welded on at the top of the back where they were probably mounted. They also have non painted (rusted) tabs at the base where they were probably fitted in a slot of some sort. Some rust if the backs and an overall nice patina. Right at 11\" tall each. With 1\" spacing between letters the sign stretches over 34\" in width.
