This Tuberculosis poster, created during the Wall Street crash, features a medieval bell ringer and the famous Tuberculosis logo with the message: "Buy Christmas Seals, Fight Tuberculosis." Christmas Seals, used on mail during the holiday season, raised funds and awareness for causes like tuberculosis and child welfare. First introduced in 1904 in the U.S., they are considered "Cinderella Stamps" in philatelic antiques.
