Jacopo Robusti (Tintoretto) lived from 1518 – 1594.  This card is from somewhat later than that, and is not really a postcard but could be used as one if one was so inclined.  It measures 5-1/8″ x 7-1/8″ and the reverse is almost entirely taken up with extensive captions in five languages.  We do not know where the card was published.  No (human) writing on it, so not postally used.  Grade: 1
