Antique black Americana bronze Letter Opener 14 Inches Long Made In use 1915

This was the first piece made of this beautiful depiction of a black boy on a letter opener in 1915 authentic original there have been several copies made later in the 1920s but this is the first one it's 14 inches long made a solid bronze hollowed in the back though when they poured the mold, it has a great patina to it. I think it was painted black at one time, but it's worn off of most of the bottom of the letter opener, but it's in excellent shape for its age.
