In an earlier post several days ago I mentioned a pharaonic head in red jasper that’s up for auction at Christies on Dec 7. Finally located the Christie’s catalogue online (it’s Flash only). In that catalogue the provenance is listed as “Acquired by the current owner, Paris, 1977”. There are three publications listed on the item (two in German) all post-dating 1998, and which all look like exhibition catalogue entries. There are other possibly dodgy items (“the provenance has too many red flags”) too.
