I got a copy of this and also one for my dad who read comics in this era and BP is his favorite character. The Billy Graham art is so raw and stylized, it looks like underground comics art in places, I love it. I do wish they had just done a Don McGregor omni with Jungle Action, Panther's Quest and Panther's Prey, all great stuff.
Actually his first appearance is jungle action 5 young election 6 is the start of the Panthers raise Ark from six song but his first appearance in Jungle action is fine I have the issue and the whole series
House of X / Powers of X by Jonathan Hickman is a great place to start for Modern X-Men but otherwise I agree with the Uncanny X-Men Omnibus vol. 1 by Chris Claremont as well 👏 Joss Whedon’s Astonishing X-Men is a pretty new reader friendly X-Men book as well :)
