From an Art Nouveau stained glass book, with only copies of black and white renderings, it was a hard sell to the client, as they had a hard time seeing it's potential. Ultimately they were quite happy. This was a more difficult design than first thought, with many leading challenges, I learned quite a bit from this panel. You can find this pattern in An idea book of Victorian and Art Nouveau Stained Glass, President Press.
