Interesting old Hankies (silk?)

Three unique and special handkerchiefs from Button Bettye's collection! All of these are approximately 12" square which I will do my best to describe below. Mom could easily give us the exact specs, but I am just guessing based on what I've learned from her. #1 is a beautiful white on white silk (pretty sure!) that uses a few stitching techniques. The edges are scalloped all around, finished with an embroidery stitch. The design and workmanship seem to me to be Asian with both cutout and pulled thread decorations. I don't see any flaws on the item, but I hesitate to say it's older than 20th Century. #2 is likely silk fabric, white with a 1" border of beige lace attached. The embroidery word, flags and flowers in one corner gives it away - Souvenir de (of) France - thus probably a gift shop item. There is a minor flaw or snag in the fabric. While clearly mass-market, it is still interesting and collectable - I'm guessing early 20th Century. #3 is flawless white embroidery on white fabric (which could either be raw silk or fine linen). In one corner, there is a large embroidery of a flower (guessing a peony) with a spray of buds and leaves amidst interesting pulled-thread geometric design (perhaps a lattice?). Tiny decorations are in the other corners, and it has a stitched scalloped hem. This one seems pretty old. Add to your collection or use as a unique gift for a bride's trousseau.
