The two figurines have numbers pressed into the porcelain and signature The signatures have scratches and are hard to read even with a magnifying glass. I believe that they were made in Germany at the beginning of the last century and are replicas of the famous Hummel figurines. I do not know if they are siblings but thought they could be.

The original photo was taken on 2-10-2019 at 10:00 AM with Sony DSC-HX200V, f/2.8, 1/30 sec, ISO 800, focal length 5 mm in window -light. I repaired some small spots where the porcelain was damaged and replaced the background to emphasize the couple.
