If you look on Loetz.com under the decor index, they list Papillon in the Pre 1900 category and also in the 1920-1940 decor list. If you click on the decor name in the 1920-1940 list you will see examples there which are more, in my opinion, like the decor application on your bowl. The shade of green also strikes me as a little later green... but that can also just be pics....
