A rare copper engraved panorama of Rome taken from the really uncommon “Sachsischer Postillon” a kind of historic-geographic magazine published in Vienna in 1784. At top the portrait of Holy Roman Emperor Frederick III and a key to 82 point of interest numbered on the view. The author is George Hisler (signed in the lower right) who drawn Rome in curious German stile easily visible in the shape of the roofs and bell towers. Central fold as issued. In very good condition.
