Tricoteuse Hollandoise; Jean Georges Wille; print; Frans van Mieris I (After); 1757

This is the other print from the pair. Unfortunately, the frame is missing on this one. It does have the original glass and backboard, just no frame. I believe that these are original prints - they certainly have a lot of age. i wonder if they have any monetary value? i know that they were treasured by museums and collectors in the 1800s, up until the middle of the 1900s, but not so much since then.
