If not familiar with the Renoir, Richard Guino (1890-1970) intercourse relating to the Renoir bronzes, best-read link as cited below, it starts out, "RENOIR dallied with sculpture early in his career, but the bronzes for which he is famous were not modeled until just before his death in 1919, at the age of 78, by Richard Guino. Nudes, mainly, they are as recognizably the master's work as his canvases - the models and poses are the same, the surfaces even evoke his brushwork as it was in the late years." If interested, though much other is written, I strongly suggest this N.Y. Times link; https://www.nytimes.com/1984/11/02/arts/art-bronze-sculptures-of-renoir-and-guino.html
Also, this link here, numerous prices of these at big N.Y. sales'; http://www.youvalyou.com/Sculptures-auction-price-results-x-RENOIR-Pierre-Auguste-1841-1919-.aspx

This particular offered bronze is obviously from a highly recognized painting, a fully finished but trial piece, as unique. For whatever reason, it was never multicast, editioned, and as such, a one-off, a rarity. It has been outfitted to take a base, likely, it has never had one. Fine condition, untouched natural color and surface, no markings, no bruises. Elderly gent's property, a true auction with no reserve.
