A few examples of various cover art from the novel Spock, Messiah!
First released by Bantam in 1976, this is known as one of the all time worst Trek novels and for good reason. Despite this, it has a certain retro charm and popularity with novel nerds (such as myself.) Much like many of the earliest novels, this is but merely a product of its time and now seems irrelevant especially with so much established canon since the initial run of TOS.
…starting on the alien landscape for my upcoming portrait of James T. Kirk and Mr. Spock, because when i’m stressed drawing alien landscapes calms me down tbh
