Showa Retro Embroidered Scalloped Handkerchief Likely a thin cotton material. I believe this was a souvenir from my father over 40 years ago, part of a set with other patterned handkerchiefs. It has been stored for a long time, but it is not unused. There are some stains due to aging. I soaked and washed it with an oxygen-based bleach.
