It seems to be the work of a famous doll maker. I believe I purchased it here at a bargain price. It appears to be quite old. It looks like it's been tea-dyed. It's not dirty, it's tea-dyed. Thank you for looking. After further research, it appears to be the work of Seiko Tabata. It seems to be over 20 years old. Angel doll, with a signature on the foot.
