I'm trying to find information (and possible value) about a sketch
signed by Renoir.  It's approx 8x13, four nude men, one in the
forground and three in the background, possibly in pen and ink.  It
looks like a signature of "Renoir" on the lower right hand corner.  On
the back of the frame stamped Emmett Johnson, Decorative Art,
Charleston, SC. (framer).  Written on top of frame "Renoir, 1887)
