Quite a collection! There are a couple of sketches here I hadn't seen before. Thanks for sharing!
Nice post, Cap'n! I really like the Iron Man and Big Barda pieces. Sersi and Gorgon and cool, too. Did Kirby really draw these just for Roz?
Well, I snuck in a couple that weren't in the Black Book, but, yeah, most of these (and many more!) were in a blank sketchbook like you find at bookstores, art supplies, wherever, and he filled one with sketches of many of his creations, and gave it to Roz for Valentine's. Jack was beyond cool!
