Thanks, MG. I'll delete it. But ....I like it the best.
BTW Henri Rousseau was a post-impressionist, like Vincent van Gogh. Van Gogh was a post-impressionist painter, but he's also listed as an impressionist...
For the 'PURE', impressionist painters, those who developed their impressionist style without interferences from any other style, the list, with the risks of using a dangerously simplistic purism, would be reduced to only three names: Monet, Pissarro and Sisley.
