Mark highly recommends (and — full disclosure — has an article in) the new, 31st issue of John and Pam Morrow's splendid Jack Kirby Collector. The Morrows have gone to a larger, 10" by 14" page format which will be a bitch to store but which shows off Jack's art to great advantage and which he would have loved. (If Jack had had his way, the average comic book would have been around the size of the Jumbotron in Times Square. He was excited when the industry started experimenting with "tabloid" sized comics in the seventies but disappointed that they used them primarily to reprint material drawn for the conventional page size.) Anyway, if you're at all interested in Jack's work, it's a must-have. Here's a link to the TwoMorrows' site, which also handles other fine publications of comic book history, such as Comic Book Artist and Alter Ego.
