Can be spartan or with beautiful photos in a sort of National Geographic style: they are the guides that accompanied me during past years to discover all the countries I have been lucky to visit so far.
Sometimes it happens that I pick one of them and find myself absorbed in a journey full of memories; between the pages, just like a memory bookmark, entrance fees of a museum or a park explored at that time that has muted colors, hotel and restaurants business cards, some airline boarding pass that no longer exist.
You never stop travelling...even browsing through the pages of an old tourist guide.
