Dear Cinemate,

Thank you for your help. My sincere apologies for the delay with the appraisal.

The presented object appears to be a painting made in oil or acrylic paint on canvas with measurements of 26 x 28 mm. The painting depicts a landscape with trees and is monogrammed with the letters "K. K." 
Sadly no additional information for an artist with this monogram fitting in style and motif is given by reference books and databases. 
Comparable objects were recently offered and sold on the international auction market. 
This piece is in good condition and there is no serious damage visible in the images provided. This piece was made in the middle or second half of the 20th century.
A fair market estimation would be between 200 to 400 USD.
This estimate is based on actual recent past recorded auction sales of comparable items. Retail "asking prices" can be higher and may vary.

With kind regards, 

George
