Mary500, I too believe that Carter took something from the tomb--probably on the evening he, Carnovon and Lady Evelyn went into the tomb before the offical opening. But whatever he took must have been small, unimportant items. A few years ago, Highclare was renovated. (Highclare is the home of Lord Carnovon) A "cache" of things, obviously taken from Tutankhamen's burial, was found--but again, it was very unimportant things---a bead necklace, a small bracelet, several other things. Thieft from the tomb was the obvious choice--nothing in the cache was offically recorded. If Lord Carnovon took things, why not asume that Carter and Lady Evelyn did the same?
One thing that has never been explained, though, is a head of Tutankhamen, showing him arising from a lotus. It was not recorded, and was found in a crate used to store wine. Carter claimed it to be a "mistake", that it was intended to be recorded. He never explained how it got in the crate or what was to become of it.
All in all though, Carter did a magnificant job in clearing the tomb. Brenson's photographs of every item--let of them "in situ" are a wonderful record of the tomb's contents.
