Let the Caped Crusader lead those birthday greetings as you hang this jumbo Add-An-Age letter banner across the doorway or right above the party table. It features Batman in his action pose printed on it. Separating the words “Happy” and “Birthday” is a cutout with an open space where you may add the age of the birthday celebrant with the included cardstock numbers. You can even reuse it for years to come by simply changing the ages!
