Every card has a special job—at least, in this house of cards.
Wide Card is a postcard, traveling to faraway places. Round Card is a price tag. Tiny Card is a raffle ticket. Giant Card is a folder for important office work.
But what can Little Card and Long Card be? They know they must be something important. When their letters finally arrive in the mail and reveal their special places in the world . . . Little Card is a birthday card! How exciting! He loves birthdays. And he loves birthday school!
