Don McGregor may have created the whole concept of the comic book as Graphic Novel with his epic treatment of the Black Panther in Jungle Action in the early 1970’s. There’s no evidence to back that up as powerful as this horrifying Black Panther story from Jungle Action 21, so just check it out already!
If you find collecting the individual issues to be a bit pricey, we see the 2010 Marvel Masterworks: Black Panther Vol. 1 in stock on Amazon all the time.
Or, put the Marvel Masterworks Black Panther Jungle Action HardCover on your want list at My Comic Shop.
