Dear Jozef,

Thank you for the additional information. This is a watercolor depicting a a standing nude. This drawing was probably made in the middle of the 20th century. The drawing is not clear readable signed in the right lower corner. A possible reading could be Eonder.
This piece is in good condition and there are no serious damages visible.
An estimation would be between 50 to 100 USD.
This estimation is based on actual recent past recorded auction sales of comparables. Retail "asking prices" can be higher and vary.

With best regards,
Georg
