The Three Blind Mice ★★★

This is black and white, snappy, UPA style public service announcement for safety procedures produced by the NFB in 1945. What really stands out is what year this was made - 1945! It really feels like something that would have come from the 50s with its snappy jazzy score and hepcat attitude.
Grant Munro was one of the animators helping George Dunning and you can see both of their styles.
I don't know why but my favorite part was probably the spinal cord sequence.
