I’m not sure if they actually stand like this in real life but this vintage drawing depicts a turtle standing on his hind legs and balanced on his tail. In the original drawing he was holding a letter on the tip of his nose, so I suppose you could place something there when you use this drawing. It’s a shame that its so little but in some ways that makes it easier to use this public domain turtle drawing in your next creative project. In 1921, children all over the world were enjoying The Peacock and the Wishing Fairy and all of the wonderful illustrations it contained from Dugald Stewart Walker (1883-1937).
