Art history is popular even among business people. If you want to look cultured, you should be able to tell the difference between Impressionism and Cubism, for instance, and should know the right book to recommend to your colleagues or business partners if you need. A History of Pictures written by the celebrated artist David Hockney and the famous critic Martin Gayford is one of my favorite ones, allowing you to understand the fundamental connections between pictures that have appeared not chronologically, but almost randomly at various times all over the world. "Any picture is an account of looking at something," says David, comparing the drawing of bulls on Lascaux cave in c. 15000 BC and the oil painting of the owl by Picasso in 1952. Fortunately, you can get A History of Pictures for Children which is kind of a concise version of it. If you can invest yourself in becoming a smart business person, why don't you get both versions of A History of Pictures to make your cultured talks more sophisticate and clear!
