I am looking to start putting something up on the walls. However, I don't really know where to start (apart from trawling catawiki). I am sure that there are many resources on the web and otherwise. Can someone give me an idea of where I might start? I am generally interested in non-abstract art - impressionism and similar is fine. No particular subject matter although I think my wife prefers no portraits or anything too serious - no Max Beckmann for example (although I do like him). I tend to like JMW Turner, dutch works, watercolours etc.. I appreciate any assistance with this.
