I have two etchings I think were given to my parents in 1931 for wedding present.
On the back of each is a sticker marked:

Genuine Etching by Boyer titled "The Rivulet", Paris Etching Society

The other is titled "The Limousin, France"

On the bottom left hand corner of each etching is a circle with the letters SLS inside the circle.

Can you tell me anything about these and their possible value.

Here's my usual C&P on this subject:


One of the best resources that I have found concerning Paris Etching Society is from Google answers, located HERE (http://answers.google.com/answers/threadview?id=39718).
The response from scriptor-ga is very insightful.

Basically PES was set up by Sidney Z. Lucas, hence the SZL mark. He owned a printshop in New York in the years 1940 to 1960 where He
produced a large number of prints after old etchings.
Generally, prints by Mr. Lucas seem not to reach very high prices.
At the end of the day they look nice, but that's about it.
Most of what is talked about them is from people "boiler rooming" the price on the supposed French history.

I hope this helps.
