Picked these up today. Cant find any info on the Renoir but it is of very high quality and in a sterling (835?) frame. Cant find much on the others either. Any help is appreciated, thanks!
The Renoir reproduction painting you have is from a larger painting entitled "Madame Charpentier and her Children (1878). The backstory of the original can be found here: Articles - Impressionism: Renoir
