I've always loved the thrill of an Advent Calendar. Here is a contemporary take on an old tradition from the French author/illustrator team Jean-Luc Fromental and Joelle Jolivet who brought us the fabulous 365 Penguins. 24 Penguins Before Christmas is modern and fun and very European in its unique 3-D diptych format.
The Calendar features the characters from 365 Penguins, and comes with a tiny little book, a page to be read each day corresponding to the advent window and the little surprise dwelling within. Amazon has it right now for a steal, you can find it HERE.
