Many fine bulino engravings done by hand in Italy from the likes of Creative Arts, Fracassi and others. The artwork is amazing, tedious, and very precise. I read about one engraving, IIRC it was an elephant on a double rifle, where the process comprised of over 1,000,000 "dots" of the bulino tools and took the better part of 6months+ in time
