This special watercolor painting commemorates the 1951 Beechcraft Model 18 airplane, also known as the “Twin Beech,” which was a 6- to 11-seat, twin-engine produced from 1937 to 1969 in the United States. During and after World War II, over 4,500 Beech 18s were used in military service, becoming, in the post-war era, the pre-eminent “business aircraft” and “feeder airliner”.
