New York: Imperial Publishing Company. A complete section (1 of 2) of the Genito-Urinary and Rectal Regions Stereoscopic Studies set. This section (which is complete) consists of twenty-four 7 x 9 inch cards plus a Title/index card. Each oversized card has a traditional silver gelatin stereoview (stereogram) mounted at the bottom. The top portion of the card has a printed explanation of the stereoview, and a pasted label noting Section and Card numbers. The card set is overall in fine condition, noting that several of the cards are on a darker card stock (either sunned, or perhaps from another set). The whole enclosed in a box with ribbon for easy removal (minor wear and label fading to the box). Near Fine. Photos Mounted on thick Stock. 
These stereoscopic study sets were issued by a variety of publishers (mostly Imperial and Edinburgh) towards the end of the 19th/early 20th century. They served as didactic (educational) tools for anatomy students at a time when actual cadavers were becoming more difficult to source in some parts of the country. Not only did they provide a three dimensional view, but they were in some ways easier to use - without the smell associated with preserved cadavers.
Each stereoview is keyed with small numbers marked in the negative. Each number is identified in the printed text for easy identification.
