Below we have a closer look at the face. That face... which seems to resemble Nimoy somewhat less than last entry's did Shatner. I would probably put this at the bottom of the set as far as capturing the features accurately, but once again, the style in which it is rendered (Kelly's unique look) probably renders the complaint moot. Who am I to tell him how he should have painted it? All I can say is, when my 17 year-old self looked at it for the first time after getting the set in the mail, I thought, "man, that doesn't look that much like Spock!" That is probably akin to someone looking at a Picasso and saying "why does that man have both ears on one side of his face?" Oh, the ignorance of youth. What say you? Was I right? Or just irrelevent?
Update: As a bonus, I am retroactively adding to these portrait posts the salute that Starlog did for each actor in their Trek 25th Anniversary Issue, which came out in October of 1986 (just before the December release of "The Voyage Home." Below is their salute to Leonard Nimoy, most famous for creating the compelling alien character of Narab on "Zombies of The Stratosphere" in 1952, and also Mr. Spock on a TV show in the late 60's called "Star Trek."
