Impressionist painting of a wave has writing

[MTB_forums]

In the dream, I was looking at a painting. It was done by my old airbrush instructor, Sol Dember. As an airbrush artist, he focused on doing things in a realistic manner. He had produced a watercolor painting of a wave; I looked in close at the wave, the details were a bunch of squiggles. Looking in even closer, I believe it was actually writing of some sort. I did not recognize the writing, it was not English characters. I remember commenting "wow, that's a really new style for you" to him.
