Possibly, you Brits know about this.
The BBC and another organization have photographed EVERY publicly owned Oil Painting in Britain (approximately 212,000) and placed them online on the following website!
Your Paintings (meaning the people of Britain) is the title of the collection. Enjoy!
Famous and unknown works are included. Over several years, the organization searched out small collections and large. Egg tempura works are included.
There are slideshows, search engines, etc. Fantastic!!!!!!
