The Vaporetto

I'm currently rereading Where is Susan? In Venice, Midge loves riding up and down the river on the vaporetto, the water bus. She thinks it's a great way to go sightseeing because it doesn't involve walking. The girls go up and down the river three times before Susan manages to persuade her to get off and go to St. Mark's. I came across this photo from 1965, so I imagine that this is the model of water bus that they took.
