From 1973, this battle scarred cover by Gil Kane and Ernie Chan for Conan the Barbarian #30!
Notice the note to inker Ernie Chan on the bottom: "Ernie - Keep cleavage delicate - light lines".
I always found this cover striking because of the giant purple bat-like creature in the background. Also the angle of Conan, as if he is on a hill with a downward slope.
Actually a lot of Ernie Chan's delicate line work was lost in the full color process! The bat had a lot of cross hatching and even the rocks were full of lines. But it's one of the classic Conan covers - each of the first 35 Conan covers were gems. Nuff Said!
