Here is a lovely small frontispiece etching and some lush and wonderful mezzotints by Jan Ladmiral, pioneer of early color printing, drawn from the NYAM copy of Icon durae matris in concavâ superficie visae, ex capite foetus humani octò circiter à conceptione mensium, desumtae; ad objectum artificiosissimè praeparatum à clarissimo viro Fred. Ruyschio by Jan Ladmiral and Frederik Ruysch from 1738.
