The Doge's Palace and Grand Canal, Venice

Gorgeous scene of Venice, one of my favorites.  Pastime puzzle cut by #11 of Parker Brothers, Salem, MA 1929.  Plywood, interlocking, cut along color lines with 60 figure pieces.  Artist is Gaston Roullet. Marie Anatole Gaston Roullet (1847 – 1925) was a French painter and illustrator, appointed official painter of the Colonies and the Navy in 1885.
For 500 p. Pastime puzzles, the number of figure pieces should be @60, 12 figure pieces per 100 puzzle pieces.  So, maybe, box label lists 500 pieces to reflect the 60 figure pieces cut, whereas puzzle actually has 615 pieces.  #11 didn't cut enough figure pieces that day to market puzzle as a 600 piece puzzle.  That should be @72.
