This 70 Pfennig blue stamp from the Federal Republic of Germany (Deutsche Bundespost) depicts Wasserschloss Mespelbrunn, one of Germany’s most picturesque moated castles located in Bavaria’s Spessart Forest. Issued in 1977 as part of the “Castles and Palaces” definitive series (Burgen und Schlösser), the design showcases the castle’s Renaissance tower and surrounding waters in a minimalist line-engraved style. These issues were widely used in everyday mail and are prized by collectors for their clean architectural renderings and subtle color variations found in later printings.
