From the man who brought us The Very Hungry Caterpillar comes this wonderful Pop-Up Advent Calendar for the Holidays. Based on Eric Carle's popular Christmas story 'Dream Snow', it's the perfect way to count down the sleeps to the big day. Open a window each morning to reveal a new decoration to add to the tree that stands in the middle of the calendar and by the time December 25th arrives, you'll have a very dreamy holiday scene.
