Here's a technique that you'd only find in a Fleischer cartoon. In Organ Grinder's Swing, de facto director Dave Tendlar chose to simulate a camera shake by flashing 2 different backgrounds - one normal and one distorted - shot on alternating exposures.
This was a smart move on Tendlar's part. (assuming it was his idea) Why you say?? Generally speaking, overlapping the actions of a camera shake and character animation would have weakened the action of the punches and lessened their impact. And for sure the action of Olive in the distance would have been lost.
See it in motion...
