Pair of 1920s Art Colony Industries Cast Iron ‘German Shepherd’ Bookends

Circa 1929 cast iron German Shepherd Bookends with a copper finish. Art Colony Industries and Hubley both made these examples, though these were likely made by the former, but no markings confirm.
Nice vintage condition with patina consistent with age.
