Was all that high school math 'really' necessary? Not for the darling dame with the red hair and blue eyes, looking yummy in yellow, on this huge, humorous, lovely to look at and laugh with card. The years might keep adding up, but she's taking no notice even if she could properly calculate them, because she's not looking a year older, herself. Wish someone special the sum total of your big admiration and giant good cheer by sending them this sexy, retro, stylish, super-sized and colorful birthday card. Complete with extra-large and hard equations on the inside.
