vintage Swiss lace edging hankies, fancy handkerchiefs w/ New Glarus Wisconsin label

Lot of three vintage hankies with fancy lace edging (maybe nylon?) I don't think it's cotton lace? These are 18" square.

Label is Upright - Swiss Product, probably mid-century? These do have some yellowing, they've never been used or laundered, so I've left them as I found them.
