A photograph of King Alexander I of Yugoslavia from a postcard in my (the uploader, Khu'hamgaba Kitap's) personal collection. The postcard itself is from the 1930s or so, and has no indicated author. The photo was edited to be more clear and was adjusted to fix minor mistakes to the photo associated with its age.
