I first encountered the paintings of Louis Comfort Tiffany, who is renown for his stain glass work, at the Charles Hosmer Morse Museum of American Art in Winter Park FL. The museum's website is http://www.morsemuseum.org/, They have a whole gallery devoted to Tiffany's paintings and about 15-20 are on display. Most of them were done before he became famous for his stain glass work. By the way, Tiffany's father founded Tiffany Jewelers.
When I visited the Smithsonian American Art Museum in Washington DC 10 days ago I saw a very nice painting by Louis Comfort Tiffany painted in 1873 and titled Market Day Outside the Walls of Tangiers, Morocco. I'll show you my photo of it since the colors are much truer than the image on SAAM's website at http://americanart.si.edu/collections/search/artwork/?id=24107.
