These are from Bernhard Siegfried Albinus Tabular Sceleti et Musculorum Hamani , originally published in the 1700’s.
I’m pretty sure these are not that old, but are printed on hand laid watermarked paper, that look to read Hamilton
Victorian. Some of the photos show the paper and watermarks. There are 7 plates 1,2,3,5,7,8,9, with the full sheets
measuring 15” x 11”, with tape residue on the back of some and a few small tears on the edges of others. SR
