What is the value of an old "original etching" called Dans les Artennes by Charlot with a triangle on the left lower edge containing the letters SZL. On the upper right corner, in very small print, is "Copyright 1935 Camilla Lucas 1935 - NY-USA" . This is a picture of a river flowing past a house on the right-hand side with trees on the left side and a windmill in the distance. A small wooden boat is partly visible on the bottom right of the etching. This is in the original frame and in good condition, and has been in our family for four generations.
