When at the Museum Boerhaave in the Netherlands for an Auzoux conference earlier this year, I stumbled upon (and photographed) this wonderful watercolor painting from 1803: "Petrus Koning with his Master."
Caption card reads:
Petrus Koning began his career as an apprentice to the Utrecht professor of anatomy and obstetrics, Jan Bleuland. They are depicted together here amid the University's collection of wet and dry human preparations.
