Hello, this item is a vintage watercolor depicting a Parisian street scene, likely Montmartre, with architectural details resembling the Sacré-Cœur in the background. The composition and palette suggest a 1920s–1930s style, reminiscent of the light, bustling urban views popular with artists of that period. The piece is signed in the lower right, appearing to read “Camille Rousseau,” and bears a label from Bernard Pictures on the verso with lot numbers, which may help trace its provenance. The dimensions are approximately 28 x 35 cm.

If authenticated as an original work by a listed French artist of the interwar era, such as Camille Rousseau, comparable Montmartre street watercolors tend to fall in the range of $400 to $1,200 USD, depending on condition, artist recognition, and market demand. The style shows similarities to works by artists like Jean Dufy, which may increase interest if the signature and provenance are confirmed. Verification of the signature and comparison with known examples of Rousseau’s work would be the next step to determine accurate market value.
