Monster (manga)
Written and illustrated by Naoki Urasawa, "Monster" was published in "Big Comic Original" from December 1994 to December 2001. The 162 chapters were periodically collected into 18 "tankōbon" volumes published by Shogakukan, the first on 30 June 1995 and the last on 28 February 2002. While writing "Monster", Urasawa began the series "20th Century Boys" in 1999, which would continue after "Monster" had finished. "Monster" received a nine-volume "kanzenban" re-release between 30 January and 29 August 2008.
Godzilla (comics)
From March 2011 to February 2012, IDW published their first "Godzilla" series, a 12-issue series called "Godzilla: Kingdom of Monsters". Originally going to be titled "Godzilla: Monster World", the new series launched with a painted cover by Alex Ross, as well as a record 100-plus variant covers that were mostly retailer incentives. This promotion allowed comic book shop owners to have personalized variants featuring their store being demolished by Godzilla's foot if they ordered over 500 copies. "Godzilla: Kingdom of Monsters" #1 was therefore able to sell out of its first printing. In August 2011, IDW released a one-shot comic called "Godzilla: Kingdom of Monsters 100-Cover Charity Spectacular". The comic featured all the unique covers of the comic book store-smashing variants of issue #1 via a cover gallery. Proceeds of the sale went to benefit the International Medical Corps for tsunami relief in Japan. On September 2011, they began collecting the series as a three-volume trade paperback collection. IDW plans to release a deluxe trade paperback of the entire series on July 2, 2019.
