I am only aware of one set of book ends. Each book end was acquired separately on eBay to make the pair. One was polished up, the other was allowed to acquire its patina. They are from L. C. Smith & Corona Typewriters, Inc. They are labelled as “Awards”. They have the 3 horses motif on a plaque. I am not sure if they are copper or just copper colored. The pair weighs 3 lbs. They are 4 1/4″ wide x 4 1/2″ tall.
