A lot of the sports teams have things called fat heads you buy-em and you can stick-em on the wall.
Maybe you can have some made up of characters and sell them. just an idea
The actually do sell some.
I’ve seen some Batman (Related to the arkham city.) and some Call of duty stuff.
Also, they have some Skylanders for littler kids.
EDIT: I just saw some online for Gears of War!
very cool
