Thank you for submitting your item for appraisal. This appears to be a terracotta bust of an african woman, partly gold colored sheet metal gilded, inscribed at the unterside "?? Woluki" or Woluka or Wolukas or similar. This bust will most likely be the work of a second half 20th century art student, the artist is not listed. There is some naive decorative charm to it, which should justify a low estimate beyond the decorative or sentimental value.
The estimate is based on similar sold or offered at auction.
