I've viewed the several links to video of this exhibit and I must say it's amazing. After years of serious study and interest in the subject of the exhibit, especially the asassinations, I think I have a very good feel for what happened. But there is nothing like seeing the material artifacts , even for me via video, to convey the immediacy and reality of it. Many presentations of the materials in books are in black and white, and seeing things like the bayonet, revolver, bullets , and IF personal items in color really does make a differnce in perception. I know it's naive to be surprised at seeing the true artifacts in color, but the awful reality really struck me this way.
Again, overall, it looks like quite a thorough effort, and I hope it's a success; a success in terms of educating the Russian populace , as well as other viewers, about the true history of that time.
