Caillebotte died at 45 and left nearly 70 of his friends' paintings to the French state, including several by Renoir, thus helping ensure his exposure and eventual critical acclaim.
I remember a Monet of people rowing on a river, a Pissaro of a quay and a bridge on the Seine, a Tahitian landscape by Gauguin, and a charming Renoir of a young girl in profile with long yellow hair hanging down her back.
