This pair of Venice views was executed around middle of 19th century and despite the absence of a signature are typical works by  

good listed Austrian landscape and cityscape painter J.Wilhelm Jankowski (1825 Bohemia - 1870 Austria), who recieved his popularity with views of different European cities and landscapes in the middle of 19th century, for exemple views of Salzburg, Vienna, Traunsee, Rome, Sevilla, Melk, Venice, Gmunden, Heidelberg , Amsterdam and others. As it´s known from artist´s other cityscapes, along with the known city views, the artist created his views of cities in free " capriccio" style, from memory, often changing the real architecture.
