1.25” with covered metal back and horizontal bar pin. Back has Chicago maker’s stamp but company name can’t be read although 1898 patent date is clear. She is pictured in fancy dress with many rings showing on her hand resting on a chair back as she poses pensively beneath her colossal frilly hat. She was famous as a somewhat risqué performer noted for throwing her garter to the audience. There is a gorgeous color button billing her as “Queen Of All Dancers” shown in the color plate section of Collectible Pin-Back Buttons. Center of button is just the slightest bit concave with a couple of fine hairline scratches at left but showing only a trace in reflected light. Button still displays glossy and Mint. Rare.
