They had a few of those mugs on display, along with the commemorative napkin that wrapped the treats inside. They were on the simple side, and the napkins were just linen with an imprint of the Tsar's face, along with a commemorative message I forget. Simple they may have been, but I can see how they would be greatly prized by the average peasant.
One light note - my middle daughter is named Alexandra, and if I remember right, she wasn't quite 6 at the time. She scooted loose from us in the middle of the exhibit, charging onto the next room. They had one of the throne chairs in there, and all the talk about "Tsarina Alexandra" in the recording over her headset was going to her head. I managed to snag her just as she was headed under the rope to sit on the throne.
If I recall correctly -- oh screw the modesty -- As I remember correctly one of the surviving killers-in-the- cellar was still attending Young Communist summer camps as late as the Gorbachev era regaling the youngsters with his role in killing "the monster" tsar and his family -- and his servants.
Also recalling correctly the princesses, having sewn the family jewels into their gowns, didn't die from the bullets. The Marxists ran out of ammo and stabbed the young girls to death.
