Originally stated to have been sold sold by online auction house / antique dealer in Kiev, Ukraine (see colour photo) but this was a misleading website posting as the actual tankard is a silver-gilt nielloed tankard* c. 1700 belonging to Vassily Vassilevich Kotchoubey, colonel of the Poltava Regiment located at the Ukrainian Institute of America (see http://ukrainianinstitute.org)
