Dear Tamara,

Thank you for your request. Thank you for the additional images and your patience. The presented object is a painting made in oil or acrylic paint on canvas with the measurements of 18 x 30 inches. It depicts a view into a forest with a river in the middle. The painting is signed probably "Demck" or "Demes". Sadly no artist with such a name is mentioned in auction record lists or similar databases. This painting was made in the second half of the 20th century.
This piece is in good condition and there are no serious damages visible.
An estimation would be between 80 to 150 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
