To celebrate a birthday, you show a stack of business cards with a drawing of a cake on the back of the outermost card. The guest of honor initials the cake and lights the candle by drawing a flame on it. She makes a wish and blows upon the card. The drawing changes into a half-melted candle that's just been blown out. The spectator's initials, which remain, are the icing on the cake, so to speak!
Contains: 12 sets of business card stickers and instructions.
