Antique framed artwork titled Under the Glowing Moon, featuring a moody seascape with a sailboat illuminated by moonlight. This early 20th-century piece (circa 1905–1925) bears a copyright mark for National Art Co., a known producer of decorative artworks for American interiors during the period.

The composition reflects the atmospheric tonal style popular in the era, with soft light across the water and sky creating a calm, romantic nighttime scene. The title is handwritten on the mat, consistent with period framing and presentation.

Framed size measures approximately 6 x 12.5 inches. The artwork shows age-appropriate toning and spotting consistent with its age. Frame and backing show light wear from handling and display.

A classic early 20th-century decorative wall piece with strong vintage character and display appeal.
