Fun postcard, which my Grandfather sent home from World War 2.  A reminder for the New Zealand troops during World War 2 to be careful in what they say as “Jerry” has ears.  A good play on words with the chamber pots also being known in slang as “Jerrys” and the caricatures on the pots.

I recognise Hilter on the right but not sure who the ones on the left are.  Any hints readers?  Mussolini?
