Thank you for submitting your item for appraisal. This appears to be a depiction by St. Mary with the infant Jesus, signed Christian Fibing or Febing or Fehrig and dated 1816. Another version of the same motif by the same artist but dated 1808 was sold at auction in Belgium four years ago. There is no further information available, he possibly was a provincial artist who painted religious paintings for a living. The estimate is based on this recent auction result.
