Two works by the famous Venetian painter Canaletto, which have been owned by a succession of bankers, will be sold during Sotheby’s Old Masters sale in London on December 4, 2013. The identically sized canvases both show views of the St. Mark’s Square and the Rialto Bridge in Venice. Created between 1738 and 1742, the paintings have been entered as one lot by HSBC Holdings Plc’s (HASBA) corporate art collection.

The paintings, which carry an estimate of $19.5 million, will be previewed in Moscow, Hong Kong, New York and London prior to the sale.
