I have a genuine original color etching (aquatinte) with a penciled signature by A. ROBERTSON, nb 37/350, provided with a small circle containing the letters SZL, representative of old houses crossed by a river (South Europe ?). On the back of the etching figure a label on wich is indicated "1937 CAMILLA LUCAS - USA-N.Y.". Can you tell me anithing about this etching, about A. ROBERTSON, about CAMILLA LUCAS ? In advance, thank you.

I have two prints that came in a paris etching society portfolio.
It says introduction by Jean Laran & copyright by Sidney z. Lucas
1945. I do not know if the prints inside the portfolio belong.The prints are not marked at all, that I can find. One is a beautiful picture of Yosemite,
shows the stream ,trees, a sheer mountain on the left & a mountain on the right with a waterfall. The other has a lake with some trees close up in the foreground & mountians in the background. Can you help me with some info?
Any value?
