I can second that, Tsarfan, being in the business for all these years. We just sent a consignment of furniture to auction, they take our information and embelish it so that it sounds better yet keeps them legally safe. We once, years ago, sent in a Faberge carriage clock which they attribited to to the Palace somehow. It was not an Imperial treasure, it was retail from the London shop. But, to some, anything Faberge is Imperial.
Alexandra's taste was not to my own either, although I try to keep my library casual , more "club like" it is still cluttered with pictures of friends, Vitrines of objects and piles of books yet to be read or sorted. The pillow case may have been comissioned by her ladies for a gift of some sort ? It looks rather pristine, so I gather it had not much use and no one wanted it after the revolution.
Still, the eagle fascinates me. I have embroidered egales in my collection but nothing like that.
