Item description for 50s Photo Postcard Xochimilco Mexico River Boat Tour?

Here is a 1940's or 50's photo postcard from the Xochimilco Mexico River Boat Tour? This one is somewhat identified with many people, and a whole bunch of boats, one named "Conghita", another "Cilia", and one called "Lolita", the only three that I can read. Picture pretty much says it all. The light spot on the photo is a reflection, not any damage. The card is in almost perfect condition, with no rubbing on the corners and edges. No other stains, tears, pin holes, or other damage. Unused, un-stamped on the back. EKC Stamp Box.
