My grandmother has a painting that is about 75 years old and I can not find who this is. Its by Jean Robert and the title is "On The Canche River". Im not sure if canche is right because some words has faded. It's a #3 with marks SZL and SLL in a circle on the back of the painting. It is a genuine original french etching. It was imported from Paris and is triangler trade? It also says L. Fle-Je Guern or Gwern. It says like site D. Im not sure if that is anything. I just want to know about this painting and if it is worth anything. The internet is apparently no use at all. He he. :p
