A Bestiary or “Study Guide to Animal Taxonomy” (not sure of title of series/folio). But here’s the first drawing on the first stone in the series, Sus scrofa:

wild-type domestic hog with taxonomy text surrounding it on litho stone

Lots of litho crayon (#4) work, water tusches, etc. This will be a color reduction print, but first doing some black-inked ones. The stone is about 20″ across x 16″ high.

Here’s from the first batch of black-inked images. This one on Rives BFK tan:

And a detail, showing the reticulation in the water-mixed tusche:

Thanks to Jack, the etching of the stone and the detail captured is amazing.
