The series was created after Marvel failed to get the rights to the Kung Fu TV show, but did get the rights to the character Fu Manchu. So Marvel creates a comic book starring his son, Shang-Chi.
The series began in 1974 with issue 15 of Special Marvel Edition magazine by Steve Englehart and Jim Starlin before it was renamed to The Hands of Shang-Chi: Master of Kung Fu, gained massive popularity and ran until issue 125 in 1983.
And now it's coming back to your bookshelf.
