One of the Silver Age Fantastic Four mega-keys, tells the Origin of the Black Panther. One of the hottest comics right now (that is still affordable to collectors).
The Black Panther explains how Wakanda is special as it is home to the metal Vibranium. Ulysses Klaw came to Wakanda to steal Vibranium and killed the Black Panther's father, T'Chaka. The young T'Challa takes revenge and permanently injures Klaw's right hand.
Mid-grade comic assessed at around 5.0, with some defects including Marvel chipping that are consistent with the grade. Very popular comic right now, in the middle of the Black Panther run in the Fantastic Four Silver Age series.
Drop me a note too if you have any other issues you want (Fantastic Four, or otherwise), and there is always this possibility that I have a copy hanging around somewhere!
