This is a Levi Strauss & Co Koveralls Two Horse Brand Celluloid Advertising Pin c 1910.
Koveralls were children's dungarees, the Two Horse Brand advertising campaign shows two horses trying to pull apart a pair of pants, to show how tough and long lasting they were.
It's celluloid over tin, the facing is in excellent condition. An overall awesome piece of advertising.
• 1 inch in diameter.
Great gift item for that special someone....especially if it's yourself.
