Antique sports award won during the scholastic career of Dr. Louis Schwartz, also a veteran on the US Navy and a championship tennis player later on in his life. Engraved copper (I think) plate on wood base, about 4 3/4" x 4 7/8" with what is certainly the original chain hanger on the back. Would date to somewhere around 1904, one of several years in which he was known to participate in the Penn Relays. "B.A.C." could be Baltimore or Boston or Buffalo or anything in that general region that fits. For winning the 200 yard relay. Don't know what the "45" indication means.
