 :*Comment ""The relevant guidance is (naturally) at WP:VAMOS"" Can't be too ""natural"" if I have been editing here for nearly seven years and have created around a dozen or so visual arts articles and this is the first I have heard of it.      
 :*Comment ""It is unlikely the Fox is the only person ever to title a painting ""Nasturtiums"" - name another notable painting so titled.     
 *Comment It seems counter-intuitive to me that to find an article about an artwork, you are expected to know the artist. One of the main reasons I would consult an encyclopedia article about an artwork is to learn who the artist is? VAMOS is inconsistent with the appraoch taken by the rest of the encyclopedia (including other artworks such as books etc.) in disambiguating by creator rather than class. A bit like the equally idiosyncratic US place name disambiguation practice, it seems to put the cart before the horse. It appears to cater well for the exceptions like the numerous paintings named ""Madonna and Child"" by forcing all paintings requiring disambiguation to use a non-standard, unintuitive disambiguation method. It is one of the strangest guidelines I have seen in Wikipedia for a while.    "
