I always love seeing Nimoy in his 1970’s mode!  Mister Cool!   Here’s a few from personal appearances.  Of course, the media still wouldn’t let Spock go at this point, as the caption to the last picture dictates “Spock, Where are your ears?” Oy!

I think that’s the Shat-Man in the background.

Probably on a convention panel.
