Did you know that Spike Lee did a BP Cameo?
Featured the "Black Panther" comic book and character by name in his 1989 feature "Do The Right Thing".

I remember that scene (and had forgotten that scene) but was reminded of the connection when Kevin Smith made a video reference in his review of BP. So it looks like Black Panther and "Black" pride were in full display way back in 1989. It was also more aligned with Eric Killmonger in it's militancy.
