This Brooch is a landscape, watercolor, I believe. I think it is quite old. These kinds of brooches were most common during Victorian times as the delicacy of the painting would have required a single-bristle brush to paint a landscape this detailed and this small. If it is Victorian or early 1900s, it is likely that someone in 1910 through 1930s removed the memorial hair and this painting from a mourning brooch and framed it in this gilded frame. The frame is gilded and the painting on paper with a glass covering. The painting is in very good condition for its age.
