Part of the sarcophagus of Ankhnesneferibre
in the British Museum.
Someone apparently working in the Ford Motor Company offices in Dearborn near Chicago and obviously with time on their hands
uploaded the image on the left to Wikipedia. A very sharp-eyed person noted: "second column from the left, five down.
Is that a real animal or a photo-shopped monster?" After a bit of searching I found the image on the right with a curious space where the monster has been inserted.
