Answer: there is no other KHWFW graffiti inscription for you to compare it to.
Therefore, your argument is completely without foundation and your notion of the glyph position being "anomalous" is both misleading and inaccurate.
As for your comment: "Are you suggesting it was painted up there in the rafters with a rotated horizontal format rather than just painting it vertically?"
clearly you have never paid any regard to my many posts on this issue of how it was inscribed, linked to an understanding of established inscription conventions.
Philip, does it not strike you as odd that if you believe the inscription to have been painted vertically that the scribe chose to break with convention by THEN rotating the glyphs 90* clockwise?
They didn't write in this way - ever!
One can infer, therefore, the inscription was daubed horizontally and it was the block itself which was then rotated 90* once in situ.
