The SGT. FURY MASTERWORKS hardcover, including all of Kirby's full stories for the book (he did covers and a few interior pages in later issues) is out now. Have to say, I don't usually pick up Masterworks books, but I'm tempted by this one (if I didn't just pick up the TALES TO ASTONISH book I'd probably get it right away). If there isn't an ESSENTIAL FURY in the next year I'll probably get it.
Much more obscure, ESSENTIAL MOON KNIGHT should have a single Kirby cover among its 500+ pages. Might be worth picking up otherwise, if you like that kind of thing.
