Welcome party guests and greet your little superhero and DC fan with this Justice League Add-An-Age Letter Banner. This features some of the most popular DC superheroes of all time in their action poses printed on it. Separating the words “Happy” and “Birthday” is a cutout with an open space where you may add the age of your birthday boy with the included number stickers. Best of all, you can even reuse it for years to come by simply changing the ages! You may place this across the doorway or right above the party table for added impact. It’s the perfect addition to your Justice League theme party.
