Nice Vintage Chicago Tribune Golden Gloves Boxing  Tournament  pin with screw back.  Undated .75" pin with raised boxing ring scene and "Chicago Tribune AA Golden Glove Tournament"  the reverse is blank other then the maker mark "Wm Schidde Co Chicago"  No date, but the style suggests these pins date to the 1930s-40s, but we could not verify that 100%.   Please see photos for more details and to evaluate condition for yourself
