Paul Klee (1879 – 1940), father of Felix.
Paul made about fifty puppets for Felix, using stuff that was to hand. My dad used to do this sort of thing.
You can see Paul’s wonderful puppets on Clive’s blog post, here.
The square was cut from a Klee exhibition at Tate Modern in 2013/14. The photograph is by Felix Klee.
