I enjoy a lot of the impressionist and fauve era paintings, but this piece here looks like a leftover palette after working on some other painting. This is what happens when I wipe my oil, and turpentine soaked brushes off on a paper Kleenex. One man’s junque is another man’s ambrosia, right?
That must explain why the painting is no larger than a napkin.
Renoir must have been using a napkin it to clean his brushes and then it just appeared out of nowhere -- voila!!! a Renoir!!!.
