A Vintage Photos Theme Park photo for the theme of smiling faces of yesteryear - photos of smiling people.

A Silver Springs souvenir folder with a photo positioned so that it looks like we're peering into the front of the boat to see the smiling passengers inside.

Silver Springs is a Florida tourist attraction -- and now a state park -- known for its artesian springs and glass-bottom boat rides.

For an earlier example, see another Glass Bottom Boat Ride photo and folder.
