ANTIQUE Early 1900s African American Man Photo Card Very Unique

Antique Early 1900s very nicely dressed African American Man Photo Card wearing a straw boater hat and what looks to be a chain that would go to a pocket watch with a whistle or folding knife (see photo for idea of what may be hanging on the watch chain). Very Unique photo and great piece of American history! Measurements are: 5 1/2” H x 3 1/2” W. Excellent condition! Box 2
