Flotsam at the crossroads of the history
The city of Ostroh (Ostrog) in what is today Western Ukraine has flown many flags over the past 900 years. Just in the last century, it was part of the Tsarist Russian Empire, then Poland, then the Soviets in 1939, then German occupation during WWII, then the Soviets again in 1944, and finally, since 1991, an independent Ukraine.
It should, therefore, be no surprise that when a local house was torn down in the city, it disgorged some interesting contents.
Some people get all the luck. The best thing I ever found left behind on a house demo was a coffee cup.
