Found a link to a gallery of all the pin-ups.
The Simonson one is definitely one of my favourites. As I’ve said before on this thead, I do enjoy his SW art in general, but I always wished we’d have gotten more “pure” Simonson art without someone else smoothing out his distinct style in the inking process.
It’s too bad that these pinups were never properly included in the re-prints (apparently some of them were). Around the time when I started properly collecting comics they at least had the sense to start including the original covers (which they didn’t before), but stuff like this was never or rarely included.
Now I’ll have to see if I can find some scans or photos of that Archie Goodwin article Shopping Maul described.
