If it was up to me and I was RICH, it would have been the lifesize C3PO and R2D2. That would be the done deal to represent Star Wars and EVERYBODY knows who those guys are.
But, I honestly only own 3 items total concering Star Wars, as big as a fan as I am and they are all I need to "represent" Star Wars for me.
They are : Darth Vader and Obi Wan PF's, squaring off in the duel.
And YODA, life size bust.
For me, that's nuff said.
