19th C. Art School Anatomy Lessons, 90+ Packed Pages Ink Drawings and Handwriten TextbooksI purchased this one on Ebay, based on a few images that made me think it might be quite a thing, and indeed it is! With nearly 100 oversized pages packed with ink drawn illustrations and dense hand written text, it was the work of a "HPB" ( monogrammed at bottom right on every page), a student of art at academy I believe, and covers a wide scope of human anatomy and physiognomy, etc. Clearly he (I presume) was referencing (probably carefully copying)
