Lithograph, Henri Fantin Latour

Another estate sale find. Unfortunately, this image was in a box of broken glass and frames. It has minor damage to what otherwise would be an amazing piece of art. It is on the most delicate paper in a folder and covered by an acetate panel. Any expertise here for this sort of thing?

 

The image is approximately 16cm x 23cm

 

This copy held in the DeYoung museum bears a pencil signature that yours lacks. Would think that influences value at the very least.
