Robert,
Thank you for the update. I last saw the collection in 1981 and I keep forgetting how long ago that truly is. Some of our posters weren't even born back then.

When was the collection sold? What prompted Forbes to return the collection to Russia? Did he truly intend for that to happen or was he going to sell at auction and the Russian government stepped in?
It was a truly beautiful collection, however, some of the Imperial Eggs were very dusty and dirty. I saw the collection I think about three times over the years that it was there and on my last visit I remember mentioning that it could use a "good cleaning".
I wondered at the logistics of cleaning such a priceless collection and how much insurance would be needed just to move it to a jeweler who was even qualified to do the work!! Forbes owned the "Spring Egg" and I remember that the flowers were very dirty. It is also so much smaller that one can imagine from the huge enlarged pictures in most books. It is a beautiful petite creation.
The book
Faberge Imperial Eggs and Other Fantasies by Hermione Waterfield & Christopher Forbes shows what was in the collection.
I mentioned all of the books I own because Romenta had asked about a good book about Faberge and his workmen. I think that
Faberge and the Russian Master Goldsmiths with text by Gerald Hill, G G Smorodinova and B L Ulyanova is very good in its explanation of who did what and where they did it. The master's marks are explained in all three of the books.
