I saw a Transformers Animated "make your own" wall calendar at one of those Shopping Centre Calendar stands. It was $16 and was square sized but not a full size Calendar.

Based on the description and images on the back, each month has a image of Animated Detroit (or other locations) and stickers of the characters you can place as you wish to create your own battle scenes. Almost brought it on the spot but I needed the cash for Universe Deluxes.
