This is a Star Wars: A New Hope Lego Chess set. It was built in April and May of 2009 and debuted at Star Wars Days at Legoland California. I am not sure why LEGO is not selling these commercially. It seems like a very fun spin on chess. I suppose you could always make your own. That might be fun, but I have a word of advice for you if you decide to make one for yourself at home. Always let the wookie win.
