Now on sale from DC Comics is a lovely paperbound collection containing around 192 pages (approximately half) of Jack Kirby's run as writer-artist of Superman's Pal, Jimmy Olsen. It's in color and despite the fact that most of Jack's drawings of Superman and Jimmy Olsen were inappropriately retouched, the power of his imagination is still quite evident. Jack was not wild about doing this particular book but he had the kind of work ethic that made it hard to say no to the folks issuing your paycheck. So he gave it his all and did the impossible: People actually cared for a time about a comic that fandom had routinely ignored and/or mocked. I'm not sure if they were good Jimmy Olsen comics but I think they were good comics, if you follow the distinction
They really showed that Kirby could be brilliant even when woefully misassigned. I did the foreword to this book, and Steve Rude turned a leftover Kirby cover sketch into a great new cover. But the reason to buy it is Kirby. Amazon doesn't have them in yet but they're out and if you pre-order here, they should send you one in a couple of days.
