Hitler's Nefertiti

While for 90 years Egypt and Germany have been fighting for possession of one publically known and famous bust of this stunning Egyptian queen from the Amarna period, the sculpture of Nefertiti (Nofretete) from Adolf Hitler's own collection has gone unnoticed because it was held privately.

These gift items feature images of this intriguing artifact. Queen Nefertiti is certainly one of the most famous women in history. She was wife of the unusual New Kingdom Pharoah, Akhnaton, and aunt of the famous boy Tutankhamum (King Tut). Is Hitler's private Nefertiti bust a recent copy or an antiquity in disguise? If the former, of which bust is it a copy and if the latter, how does this new portrait fit within the context of the other Nefertiti portraits from Tell Amarna?
