19th C. Naive Double-Sided Graphite Drawing: Pigs and Birds

This is among of a number of drawings I have listed/am listing by the same (surely quite young) maker, 1870s or so I believe,  found together in an old notebook already partially disassembled so I went ahead and separated them all. I really love the mother pig with bunch of piglets running around on this, with some darks stains at right that feel quite appropriately like mud! Nicely drawn barn in the background too, and then a couple of exotic birds in trees on reverse with tiny little nest at right. 

7 3/4" x 5 1/4" and in pretty condition, with dark mud-looking stain as noted and a bit of what I think is some green paint rubbed off of another drawing at lower right on that same side.
