When I become a real artist, people will know, because I will be able to create quick sketches like this and the eyes of the beholder will instantly understand the scene, even though the squiggly lines are nothing more than an abstract suggestion of what really was there. For years I have admired artists' signatures that use this technique. I have a much-battered copy of Bernard Shaw's play Pygmalion (Penguin Books) from 1953. The illustrations are by a certain Feliks Topolski. Scribbles, wavery lines, swooshes and swirls. A stage is set. Fascinating.
