ca. 1705 Sophie Albertine Erbach by ? (location unknown to gogm)
Her Wikipedia article, with this image, is here.
The image was extensively spotted throughout and spots away from the face were removed with Photoshop by gogm. Large regions with irregular flaws and the upper half of the right edge were also fixed with Photoshop by gogm. The partially obscured lower bodice just outside the oval and dark area in the lower right part inside the oval are from the original.
