Alan E. Alford, author of "When the Gods Came Down," states that, in the late 20th C., Robert Bauval, Graham Hancock and John Anthony West, did a "peace deal" with Zawi Hawass and in return were provided access to the "relieving chambers" above the Kings Chamber.
There they inspected the questionable graffiti and, in Alford's words, "declare(d) themselves converts to the established dogma," claiming to have seen the graffiti marks deep within the joints between the stones.
Alford is skeptical of why the guests of Dr. Hawass so readily changed their point of view in light of the fact that if they photographed these markings, which are obviously crucial to the claim that Khufu built the Great Pyramid, no such images are available as proof.
Firstly, is this story true?
Secondly, are any such images available?
