A taxidermy small brown dog, Owney, the unofficial mascot of the US Postal department, wearing dozens of medals and tags from his train car stops on his collar.

Owney was a scruffy mutt who became a regular fixture at the Albany, New York, post office in 1888. Owney began to ride with the bags on Railway Post Office (RPO) train cars across the state . . . and then the country! The RPO clerks adopted Owney as their unofficial mascot, marking his travels by placing medals and tags from his stops on his collar.
