There is a large exhibition of Paul Klee's work running at Tate Modern in London. In among the many abstracts are some cartoon-like works. I was particularly struct by one from 1922/23 called "Main scene from the Ballet 'The False Oath'"".
I found an image of this Klee work here
Does anyone know more about this ballet and who made or performed in it ? What would Klee have been seeing in the 1920s in Germany ?
