Here's links to photo galleries of MR's replicas of the ANH & ESB versions respectively:
ANH: http://www.rebelscum.com/mrvaderanhsigsaber.asp
ESB: http://www.rebelscum.com/mrvaderesbsaber.asp
Though they're replicas, they are VERY accurate & you can see much better detail to see the differences since the quality of pics is much better.
