This is a 1964 promotion for Norflex by Riker Labs using an 18th-century anatomical atlas by German anatomist Bernhard Siegfried Albinus, published in 1747/1749, and featuring detailed plates by artist Jan WandelaarVintage.

The title is Tabulae Sceleti Et Musculorum Corporis Humani and there are nine detailed anatomical illustrations. They are all in good vintage condition with some discoloration across the top edge of a few of the pages (see photos - I think it would all be covered with a frame). The outside folder has significant wear and discoloration.

This is an outstanding find and one of the coolest things to ever come my way!
