Conservationists research canvas painting featuring Maria Theresa and Lichtenstein Prince

Czech conservationists are trying to determine the value of a large painting that was found stored at a depository of the Valtice Chateau near Breclav, south Moravia. The painting dates back to the second half of the eighteenth century and was believed to feature Prince Joseph Wenceslas Lichtenstein, who owned the estate at the time, and his extended family. More intense research, though, has uncovered that the Prince is standing next to the Empress Maria Theresa and her relatives.
