Surprise your loved one with your special birthday greeting. Get started with this Jumbo Add-An-Age Letter Banner that you can hang across the room of your party venue. Separating the words 'Happy' and 'Birthday' is a cut-out with an open space where you may add the age of the birthday celebrant with the included cardstock numbers and letters. Simply change the ages with each birthday celebration to reuse it for years to come! Match this with other party supplies for a fantastic coordinated theme.
