Thank you for submitting your item for appraisal. This appears to be late 20th century large porcelain head doll with a dress in the manner or fashion of the second half of the 19th century. The manufacturers sign is most likely fictitious, it consists of something like a crossed laurel wreath, a shield mark with a large "N" and a document scroll. Most of such dolls were mass produced in South Korea and China. The estimate is based on similar offered or sold at auction.
