If you planning to go to Disney in the near future, might also check out their stores selling artwork. I can recall one near the entrance of Epcot and might also be one at Disney Springs. Disney people working in those stores can probably be a good source of information if you show them the picture of what you are looking for. I would only buy it online from official Disney stores. Various 3rd parties might be selling copies if you are looking for the real thing as some sort of collectible. They might also fake the paperwork to make you believe the item is authentic when it isn't.
