A life-size anatomical figure with flaps

The plate volume from an anatomical text book by Doctor Julien Bouglé (1868-1903), illustrating five views of a life-size adult male, With the flaps down the image is of the body's musculature from the front. On the reverse of the first pair of flaps (top and bottom of the figure) are the musculature of the back and legs. The second pair of flaps show the blood vessels, again front and back. The bottom illustration is of the skeleton with a complicated system of flaps for the ribcage and internal organs. Each feature is numbered, described in French in the original booklet (available as a download from the Bibliotheque Nationale de France). A rare survivor of a fragile publication, in surprisingly good condition considering the intricacy of its construction.
