No problemo! Just leave it blank, because the age entry is optional for our anniversary cards. On the Vintage Anniversary cards, a rose appears on the spot where the age is normally displayed, and on the Modern Anniversary cards, the age on the heart is not displayed.
For our birthday cards, the age entry is also optional. When the age entry is left blank, the Vintage birthday cards will display a balloon instead on the spot where the age is normally displayed. The Modern birthday cards will simply not display the balloon with the age on it.
