About Black Jack
*Diamond Comic Distributors has commissioned Exclusive Hardcover Editions of the first three volumes of the "Black Jack" series. Each hardcover volume sports a unique cover different from those of the regular paperback editions. The hardcover volumes also include an additional story that will not be included in the regular soft cover series. These stories have been locked away at Tezuka Productions for decades by request of Tezuka himself, and have only recently been re-released in Japan.
Most importantly, each Exclusive Hardcover Edition will be limited in number.
