Vintage grey elephant drawing done by Harrison Weir (1824 – 1906) and likely colorized by an un-named staff watercolorist. The book is from 1857 and was called Animals : their pictures, habits, and uses.
I think this grey elephant looks to be a quite friendly fellow. It’s almost like he’s winking at you and playing shy at the same time with his trunk at his open mouth. His tusks are nice, straight and white. His tongue has a bit of pink. The background of the drawing is a pale green and it looks as if he is standing on red/orange clay.
