This is a stereoscopic photograph, also known as a stereo card, from 1877. It features a woman seated in a chair, captured from two slightly different angles to create a 3D effect when viewed through a stereoscope. The woman is dressed in a long, light-colored dress with a dark bodice and a white apron. She is holding a closed fan in front of her, decorated with a floral pattern. Her hair is styled in curls, and she appears to be wearing stockings and shoes. The background consists of dark, heavy curtains, creating a dramatic contrast with the woman's attire. The overall composition is formal and posed, typical of portrait photography from that era. The card has text printed on the edges, including the copyright information and the title 'A Study in Buttler'.
