Sotheby's to offer recently discovered Canaletto drawing

[Spears]  An unsolicited phone call to Sotheby’s Paris has revealed the remarkable existence of a previously unrecorded Canaletto, Campo di San Giacomo di Rialto, to be offered in Sotheby’s Old Master Drawings sale on the 4th July. Unsuspecting its true value, the current owners have kept this rare drawing preserved – unknown to scholars - for over a century in their private collection. It comes to the market as a historic event, the first major Canaletto drawing of a real Venetian view to be offered in over 30 years.
