Hi! I have a great source for you. His name is David Tutwiler
www.tutwilerfineart.com He is officially licensed by Disney. (Making a long story short..) I met him at a model train convention in Milwaukee. He had beautiful paintings/prints of trains, landscapes....and Disney! David and his wife are great people and told me all about how they kind of fell into painting for Disney - George Lucas even owns several of his paintings! His paintings/prints are sold directly through him and then only in the Asia parks. They are gorgeous! We bought a print of Mickey with the steam train in front of the castle. I am not one who purchases art but I couldn't help but fall in love with it. Definitely check him out!
