"The leading lot in Christie’s sale of Antiquities, to take place on December 7, is an Egyptian painted wood sarcophagus and mummy for Neskhons, Third Intermediate Period, Dynasty XXI, circa 990 – 940 B.C. (estimate on request). Sarcophagi of this quality rarely appear on the market and Christie’s is delighted to offer this exquisite consignment. The last time a mummy with sarcophagus was sold at auction was in May 2003, when Christie’s South Kensington sold the sarcophagus and mummy of a priest of Amun for $1.4 million which still stands as the world auction record for a sarcophagus and mummy."
See the above page for the full story, including background information about the sarcophagus, and a lovely photograph.
