Flea Market Postcards - Camp des jeunes

This card shows the youth camping site at Lourdes and is postmarked June 1973. I've found some recent photos on Flickr but none that I can use without infringing copyright. The site is more wooded now and the style of tent has definitely changed - they no longer look as if it is a scout or army camp.

Looking at the picture the style of shorts has changed as well.
