Hello, my wikiname is Espandero. I'm from French-speaking Switzerland, thus I mostly contribute on French Wikipedia. My interests are broad but on Commons I mainly post work related to Switzerland and the canton of Valais. More info here (in french).
If you use my pictures outside of Wikimedia please use my real name, Christian David, as an indication of authorship. I'd like to be informed as well, so a message would be nice.
