The claim that Howard Vyse, or his assistant J. R. Hill, painted the Khufu cartouche found in the relieving chambers above the King’s Chamber in 1837, in order to manufacture a dated attribution for the Great Pyramid of Giza.
What the claim rests on
A single page of notes written by Walter M. Allen in 1954, about letters he attributed to his great-grandfather Humphries Brewer, an engineer said to have been present and to have objected to the painting; the letters themselves have never been produced. A secondary argument concerns the spelling of the cartouche. The case is argued most fully by Scott Creighton in The Great Pyramid Hoax (2017, with a foreword by Laird Scranton), and it reaches this wiki through The Anunnaki Chronicles, where Zecharia Sitchin reports it as established, and through The Wars of Gods and Men.
Why Egyptology treats the question as closed
The marks are gang-name and work-crew formulae of a kind not understood in 1837, they appear in sealed spaces awkward to reach and in positions no forger would choose, and since 2013 the Wadi al-Jarf Papyri have independently named the monument Akhet-Khufu in contemporary administrative documents. There is no dedicated Egyptological rebuttal in print because the field does not consider one necessary, which means a reader who wants the dispute rather than the verdict has to go to the advocates for one side and the primary evidence for the other.
