The greatest Black Panther page of all-time?

Page 18 from Avengers #73, cover date Feb 1970. This is the moment when I truly began to love the Black Panther.

A brilliant (and rare) turn on pencils by Frank Giacoia. Inks by Sam Grainger. Text by Roy Thomas. Letters by Artie Simek. Colors by ???

EDIT: Here's a good soundtrack for this page -- "Quantum" by Nik Furious 😀
