I saw this face on the cover of The Image of Black In Western Art. It stopped me in my tracks. a black CRUSADER!!..that's like a black cowboy they simply don't/didn't exist as we never see them. Right? Wrong! They - the black crusaders and black cowboys - were there as blacks got and get everywhere. So, why not a Black Crusader? Great Picture.
