Dear Miguel,

Thank you for contacting Mearto with your appraisal inquiry. The presented object is a painting made in oil or acrylic paint on canvas with the measurements. The painting depicts a nude posing in front of an undefined background. In the right upper corner, this painting is signed with the name Halbach. Sadly no further information of the biography for this artist is mentioned in auction records or similar databases except that he was born 1912 in Germany.
This piece is in good condition and there are no serious damages visible.
An estimation would be between 100 to 200 USD.
This estimation is based on actual recent past recorded auction sales of comparables. Retail "asking prices" can be higher and vary.

With kind regards,
Georg
