Holiday makers using their cameras in the 1950s

A snapshot of a group of holiday makers who have just stopped, alighted from their coach and are admiring the view and using their cameras to take pictures. There is a notice at the back of the picture, but it is too blurred to make out the wording, although it appears to be in french, so this could be taken in France. The style of the cameras, the clothes and the coach design place this picture firmly in the 1950s.
