My Jugendstil-galleries ("Jugendstil" is the German style-direction of Art Nouveau) contain many images of "pure" Jugendstil, (some links in the pure style of Jugendstil are here - 1 2 contain also other images of buildings built in the period of Jugendstil - years around 1900 - with mixed style elements,contain elements of Jugendstil and also elements of former style periods. At that time many architects were influenced by the new upcoming style and used style elements of that style period.
