Beside the road just before you get to Colossi of Memnon on the way to the Valley of the Kings.
This retired school teacher has set up a little museum beside the road to Valley of the Kings in 2005.
This is a carving of the Egyptian God Bes. It's at the inner entrance of the Mut Temple in the Mut Precinct.
You got the location correct, but the name of this area is the Mut Precinct. Out of curiosity, how did you get in? Is it open to tourists now? The head of the big statue is in the British Museum if you're interested.
