Sennefer and Queen Pharaoh Hatshepsut, Ancient Egypt Pharaoh.

According to the Louvre, where this piece resides, Sennefer was the King's head clerk, and this is his wife Hatshepsut--but NOT the Queen/Pharaoh of the same name.

That would explain why she is wearing no uraeus or other regalia of Kingship and he is portrayed as equal to her in size and importance.
