untitled rainbow drawing

This drawing is one of a pair, both of which remain untitled. Sometimes a title, or a name for a piece arises in one's mind like a bubble rising in water. At other times they require a good deal of patient research. And very often a piece will defy any attempt to name it, as it is with these two drawings, neither of which have yielded to my efforts to title them. They were both made in September 2009, as well as the obscured rainbow drawings, and the dark rainbow drawing. It was a month during which work went well.
