This is a good example of the differences between Marvel & DC, especially when it came to race relations. In the Green Lantern books, DC was just starting to address the issue of racism. They didn’t do it with a black superhero, but instead had a one-off character point out that Hal is a racist.
Marvel had already established a few black superheros by the early 70s, some even headlined their own book. Chief among them was Black Panther, who is literally attacked by Klansmen attempting to burn him on a cross. Clearly one publisher had a more subtle approach to this topic than the other.
But while everyone knows the "black skins" speech from GL #76, I think the Black Panther panel is much more powerful. It doesn’t (for lack of a better term) white-wash the issue of racism by reducing it to a soundbite. Instead it shows racism at it’s purest and most disgusting. It shows that even though he’s a superhero and a king, T’Challa was treated like any other black man in America.
