Description: From "Picturesque Bath. Illustrated by A Series of Sketches from Nature" by Caroline M.K. Stothert, 1881. Containing fifteen views described as auto-lithographs. Confused with tinted lithographs, the difference being a very regular printing pattern, suggesting a mechanical origin, is revealed under a strong glass. All the illustrations are printed in a distinctive wine-coloured ink, with a grey-brown tint.
