This picture is entitled "The Graham Children" and was painted by William Hogarth (1697-1764). Yes, the children are having fun and laughing and smiling, etc. But the main feature of the picture is hidden cunningly in a corner. Just look at that cat! One glance is enough to confirm that he (we cats can tell if a cat is a she or a he) is a true hunter. And the placement of the cat is very good, the author puts it in the background as if it didn't matter at all but yet it springs right into your attention. A truly great painting.
