As a life long enthusiast of anything Egyptian, this is, for me, the greatest museum in the world.
Gold death mast of King Sheshonq II (Heqakheperra c.890, Dynasty 22), mask. Sheshonq II only reigned for a year and he had been co-regent with his father Osorkon I (Sekhemkheperra 924-889 BC). His intact burial was found in the antechamber of the tomb of Psusennes I. Cairo Museum, Egypt.
Funerary portrait of a little girl, encaustic on wood, 1st century A.D. (Egyptian Museum, Cairo). To my mind, this is one of the most touching examples of the so-called Fayum portraits. The girl's mummy was found in Hawara, Egypt with the mummy of a woman named Demos, who may have been the child's mother.
