First Tom & Jerry cartoon where the titular duo speak.
The mustache and hair that Jerry drew on the face of Tom's picture was a caricature of Hitler.
This is the one of the few Tom and Jerry shorts to be animated by Al Grandmain. His few projects are Dr. Jekyll and Mr. Mouse (1947), The Cat and the Mermouse (1949), Tom et Jerry au feu d'artifice (1950), and Just Ducky (1953).
