Our friends over at TrekCore continue to post extremely lovely Blu-Ray high-def screencaps of TOS episodes. They've just done The Savage Curtain - not one of our faves - but I found some great shots of Kirk. Sure, it's third season and he's put weight, and he's got a terrible toupee, but it's BILL!
Look at the faces. And the pointing.
Enjoy. And click to embiggen.
