Vintage Horsehair Shoe Shine Brushes 8" and 6.5" Long

2 Vintage Shoe Polishing Brushes. The larger one is for black shoes and is stamped from the National Brush Company. It's bristles or natural horse hair. The shape of the handle is slightly convex. The smaller one is for brown shoes and has no brand stamp. I'm assuming the smaller one's bristles are also horse hair as the owner would only buy horse hair brushes. The shape of its handle is convex. Both brushes are in very good used condition. The wood handles are scratched and have wear from use. The bristles are in excellent shape.
