Felix Lorioux is a French artist that worked, as far as I can tell in the teens. 20s and the 30s of the last century. Throughout the 1930s he was chosen by Disney to draw their licensed characters in France. I’d like to see how he handled the Mouse or Donald.
I believe that these are done in watercolor.
I have to say that I am transfixed by this image in particular.
Now how could I resist showing a walking tree?
