All photos: Gerald Gurian

The first To Boldly Go: Rare Photos from the TOS Soundstage book covered season one of Star Trek: The Original Series. Now author Gerald Gurian has released To Boldly Go: Rare Photos from the TOS Soundstage - Season Two, and it’s exactly what it says on the tin—and its collection of photos are just as captivating. See for yourself!

io9 has is proud to present this small selection of pictures from To Boldly Go’s second installment. The book is a treasure trove for fans, and what’s striking is just how identifiable so many of them are: William Shatner and Leonard Nimoy preparing to face off with the giant axe/q-tip can only be “Amok Time,” for example. Or the androids from “I, Mudd” popping up. DeForest Kelley gets old man make up for “The Deadly Years.” And so on and so forth. (Except the one with Kirk’s Rock (a.k.a. Vasquez Rocks) in the background. That one could be any episode.)
