While at the Disney Store Yesterday noticed a variant on their Exclusive Han Solo and Luke Skywalker Elite Series 2-Pack. The variant has to do with the paint job on Luke Skywalker head.
• Blue eyes and blond hair
• Brown eyes and brown hair
According to the bio for Mark Hamill, he has blue eyes and had blond hair, so I am assuming the brown eye and brown hair version was the first produced and then Disney corrected it to the blue eyes and blonde hair.
