This lot features two chromolithographed paper anatomical sectional models depicting a male and female figure, presented alongside a large printed reference sheet. The reference sheet is titled STRUCTURE OF THE HUMAN BODY and FEMALE: ANATOMICAL SECTIONAL MODEL. It contains an extensive keyed index for several biological systems including I. External Aspect, II. Vascular System; Heart and Blood Vessels, etc., III. Viscera, Particularly the Digestive System, IV. Skeleton From the Front, and V. Lymphatic System. The figures are depicted from the torso up; the female figure is shown nude and the male figure is shown wearing a white waist wrap. These types of anatomical "flap" models were commonly produced in the early 1900s as educational inserts for medical texts or health encyclopedias. The items are mounted as a collection and housed in a black frame behind glass. A dealer label is affixed to the center providing historical context.
