Originally on display at the 2009 San Diego Comic-Con, The Empire Muggs Back was a charity event that saw artists creating custom Mighty Muggs that were to be auctioned off to benefit Make-A-Wish. Needless to say, the auctions were very successful and a lot of money was made for a great cause. Katie Cook's Wampa with Luke Mugg is currently available on eBay. If you are looking for a cool one of a kind piece for your collection that comes with an interesting story, this is one you really want to check out.
