This is apparently a neck-hanging apron given at the restaurant "Ima-Sa" to prevent clothes from getting dirty while eating. However, the string is short, and there are no buttons or Velcro, so how to use it is a mystery. I think it's from over 50 years ago. If you're looking for one, how about it? And please, tell me how it's used. There are two pieces. One is not in a bag and has a slight stain where it's folded. The other one is clean.
