I have two original etchings copyrighted by Camilla Lucas dated 1935. Both have a copyright mark in the lower left corner one with Z5L and the other Z6L. Both are marked Hand made Artist Proof Etchings. They both depict village buildings along a waterway or canal. They are signed in what appears to be pencil with a signature that is difficult to read. The signature appears to be Srueitt or Sruiett . These etchings have been in my family for a long time and I would like to know more about them and a value if possible. Thank you.

There's a whole bunch of threads concerning SZL and the Paris Etching Society.
Unfortunately they aren't worth a great deal, a few hundred at most.
