Recently, Armenian "history" workshops were found in Kalbajar. The investigation disclosed that "ancient history" was being made in workshops by Armenian masters.
Thus, they draw ancient letters and images, crosses on the stones and keep them in vinegar for a while. As a result of oxidation from vinegar, the stones change colours and seem old. Then, they bury these stones in the territory of Karabakh, trying to prove that these territories historically belong to the Armenians.
Note, Armenians made similar falsifications before.
