Back in this dispatch, I gave a highly-biased recommendation for a new book, The Best of Simon and Kirby, featuring epic work by Joe Simon and Jack Kirby. At the time, it wasn't out…but it is now. Check your local bookseller or order it online.
And if you're still not sold, check out this online preview. Read an early Simon-Kirby story and one of my several chapter intros from the book. Or better still, just read the Simon-Kirby story…and remember: That's the kind of thing those guys were doing when they were just starting out. They just got better and better and better and the book is full of examples.
