This and the two following are photos from inside the Lavra, the monastery area in Kiev. This area was built by Yaroslav the Wise's sons in the 11th century and includes caves where monks lie "buried". The old man's tomb, however, is found in the Saint Sophia Cathedral (where, unfortunately, you aren't allowed to take photos).
This one I bought in a store with... random old stuff! I don't really know how old it is, if it is really very old or not, but it wasn't expensive and it's fun to have something that feels authentic.
