A beautiful hand coloured engravings from Georges Louis Leclerc, Comte de Buffon's Naturgeschichte der Vogel (the German translation) published in the late 1700s through the early 1800s. This one a 'Gimpel', a beautiful bird that I must still look up.
Nicely matted & in more contemporary frames that work quite brilliantly. Each measures 8" w x 11."
'Histoire Naturelle' was one of the most expansive works done in the field of natural history.
