If it was the guy’s tomb, why isn’t his name anywhere? All the other tombs are positively lousy with art. But not this one. The one - graffiti, not official, not sanctioned - name is hidden in the equivalent of a closet and that is in shorthand even?
I don't know a ton about Khufu, but us it possible that he just didn't want as much iconography? I know it's been common for several other cultures (some of Byzantine and Islamic) to not what to have icons or representations of people. Definitely odd, and I'm not sure why almost all of the other pyramids would be tombs and then his wouldn't be.
