Pair of Relievo Ambrotypes of a Young Girl Rare Contact Printed Set

"The‘Relievo’ portraits were introduced in England in 1857 by Thomas C. Lawrence, a Greenwich photographer.
The ‘Relievo’ ambrotype was based on the relief effect that was achieved by the layering of the image plate over another image or background. The structure of a relievo ambrotype could have been single, double or triple depending on the style."
