I have a etching it says genuine etching by Martin entitled "The Dam" Paris Etching Society distributed by Turner is on the back also the number7400 and SZLOR Slz could you tell me a little about this etching?

What I can tell you right now is that we have an excellent reference link on this site concerning works done by the Paris Etching Society. It is located on the following link. https://www.askmehelpdesk.com/art/pa...ad-155531.html

Concerning anything else about the etching, then I will have to do a little more digging...

But, information about Paris Etching Society works are very hard to find.
