There was a huge Faberge exhibition here in Richmond in 1996. The Richmond Museum of Fine Arts owns a pretty sizeable collection of Faberge artifacts. But this exhibition in 1996 gathered things from all over the world. It was amazing.
The final part of the exhibition was a "pick the fake" exhibit. There are a lot of good fakes out there.
I am a little skeptical that these are true Faberges.
There's several wonderful books on Faberge's work out there. The Forbes collection book is worth having in one's art library.
