"After Star Trek IV: The Voyage Home" from Star Trek: Debt of Honor GN (DC, 1992) by Chris Claremont, Adam Hughes and Karl Story
Siskoid's Blog of Geekery covered every single Star Trek comic DC ever published (and Marvel, and Malibu, and Gold Key, and almost all the IDWs, etc.), and they don't usually offer up outstanding splash pages. Mostly, it's fair to mediocre likenesses or photo referenced art, though DC did have some good runs, especially with the movie era original cast of characters supplemented by new characters. But for art, I've chosen one of the graphic novels, Debt of Honor, the review to which you can find HERE.
