A quick mention of a few things I forgot to include on the previous Kirby in 2006 post. As Harry’s noted on the S&K Blog (another noteworthy addition to Kirby collecting in 2006) there were two separate series of books for younger readers and libraries about comic book creation. One set from ABDO & Daughters covers six comic creators, including volumes on Jack Kirby and Joe Simon. Another set from Rosen Publishing covers the creation of various Marvel characters, including volumes on Captain America, the FF, Hulk and X-Men.
And if you like your comics digital, you can get DVD-ROMs full of PDF copies of four decades worth of FANTASTIC FOUR, AVENGERS, X-MEN and SPIDER-MAN.
