A commemorative stamp is a special type of postage stamp issued to honor a specific event, person, or anniversary. These stamps are often produced in limited quantities and are designed with unique artwork that reflects the significance of the subject being commemorated. They serve both a practical purpose for mailing letters and a collectible appeal for stamp enthusiasts. Typically released on important occasions, such as national holidays, historical anniversaries, or to celebrate notable figures like scientists or artists, commemorative stamps help raise awareness and appreciation for cultural heritage. Collectors often seek these stamps to preserve a piece of history and to celebrate the achievements or milestones they represent.
