This collar is absolutely beautiful! I believe it is battenburg lace, I know it is OLD, and well-cared for. I tried to get photos of just how beautiful this is, hope I did it justice. It is about 29 Inches wide at the widest part of the shoulder, the back is about 10" in length, from the should down the front is about 18 1/2 inches. I can only see one tiny problem, which I got real close to show in the last picture, otherwise it is in beautiful condition. I can just see this in a vintage wedding!
