This is the one book I bought while in Wellington: "The Usborne Introduction to Art". It's a children's book introducing different (Western art) eras and isms to children in short, succinct sentences and lots of visuals and some links. For example, page 104, "Less is more":
"Around 1910, artists began to paint pictures which were not meant to be picture of things, but things in their own right. Instead of showing recognizable scenes, these paintings used combinations of colors, lines and shapes, put together in expressive or decorative ways. This kind of art is called abstract art."
OK, I can live with this. I had to have it, and am so glad I got it. The book speaks like I do. Very recommendable to all sort of readers.
