I'm glad you like the peasant paintings. Just like there were dozens of Harnett's and Peto's in American museums, there are dozens of van Ostade and David Teniers the Younger paintings in the British Royal collection and the Scottish National Museum.
You know, in the US we have lithographs of these artists. Royal families get the original paintings. Unlike when some of them were bought or donated, they are, now, really available to the whole country. How cool is that? The peasants can see if they really look like the Jack Kirby on Prozac characters these two guys cook up.
