Inked by Al Milgrom. Solid enough job, and some nice stuff in the background space scene, but I have to say, this may be the most boring Kirby cover of all time. There are only a handful of Kirby covers I can think of where the character isn't doing anything, and this may be the most dull of them. I think it's the almost symmetrical pose that really does it.
On the other hand, you see covers like this almost every week on books published now.
