The picture with the bridge has a number 15 stamped on the back and two signatures. One in lower left lookes like D---Valles in lower right looks like Boyer. The picture with the well also has two signatures, lower left looks like Eva Toris and I really can't make out the lower right maybe Pierre. Both have a copy right mark at the top edge "Paris Etching Society"

We know very little, My great great aunt passed away about 3 years ago and don't know the full story. Historic information is our main interest, though we would also not mind knowing the approximate value. Thanks for any help you may have.
