COLLECTIONS No 83 Ave 2017  Speleologie, Alpinisme, Explorations.  40 pp, most pages with colour photos.  This is a full colour caving magazine in French for collectors of caving stamps, cave postcards, caving phone cards, caving beer bottle labels, in fact anything to do with caving that is collectable.  The French is so basic, even I can understand it:  SB price only a fiver.
