Dear Jonathan,

Thank you for contacting Mearto with your appraisal inquiry. My sincere apologies for the delay with the appraisal.

The presented object appears to be a photographic print or serigraph on paper with measurements of 16 x 12 inches. The print depicts the castle Lichtenstein Castle in Germany (https://en.wikipedia.org/wiki/Lichtenstein_Castle_(W%C3%BCrttemberg)). This castle is an ideal example of the Gothic Revival in Germany and was mainly built in the 19th century between 1840 to 1842. It is titled "Lichtenstein" and signed by an artist with the name "Paul Zauch" It was probably made in the first half of the 20th century.
Comparable objects were recently offered and sold on the international auction market. 
This piece is in medium condition and there is no serious damage visible in the images provided.
A fair market estimation would be between 10 to 40 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
