What's the Story of the Amana Bust and Nefiteti?

Nefiteti was discovered by a german team of archaeologists working at the beginning of the last century. It was found in the remains of a workshop, which we think belon to a sculptor called tothmosis. He'd had to abandon his workshop because obviously, without the court being there, nobody wanted royal sculpture. So he left it behind and he went away. The head, almost immediately, was sent to germany,. i think, before anybody could change their mind, anyone could see that clearly something had gone wrong. And this debate has been continuing with egyptian authorities asking for the return of the bust. I'm even leaving that one side alone...
