The Ca’ d’Oro, or Palazzo Santa Sofia, is a palace on the Grand Canal.  Its name means “golden house” due to the gilt and polychrome external decorations which once adorned its walls. Since 1927, it has been used as a museum, as the Galleria Giorgio Franchetti.  Not sure when the card was mailed because it only has half of the postmark — probably early 1960s.  The stamp’s there, though.  Grade: 1
