We’ve seen comparable images a thousand times, but I highlight this silhouette – not on display at the National Portrait Gallery, yet found online (search for SARAH PONSONBY or ELEANOR BUTLER rather than the LADIES OF LLANGOLLEN) – because it is thought to have been done c1810-1823. During their lifetime! By whom? for whom? we shall never know. See the image and read about the silhouette by clicking the link. DO view it as a fuller-sized image. The detail is terrific! You can see the fluff of their hair, the folds of their skirts. Sarah has a frailty about her that, I think, puts the image later rather than earlier. She was certainly described by Anne Lister as being in poor health.
