Framed C1830 Painted Silhouette of Doctor with Skull

A rare and most unusual c1830 painted British silhouette of a doctor or naturalist in its original frame. Dimensions of frame: 31 x 38 cm approx.

This can be confirmed in the next image, which shows the silhouette removed from the frame. The only similar silhouette I’ve been able Read More...
