Cushing vs. Tarkin

Because George Lucas' "young" Tarkin looks nothing like young Peter Cushing.

I threw Christopher Lee in there for good measure because he's as badass as Cushing is.

EDIT: For comparison purposes...

Since Revenge of the Sith takes place about 20 years before A New Hope, we'd need a photo of Peter Cushing from around 1957, during his Abominable Snowman or Curse of Frankenstein days (both of which are excellent films, btw).

So, on the left we have a photo of Peter Cushing from around this time period. And on the right is what we get in Revenge of the Sith:
