Bomberg comments on the series of drawings inspired by dance halls and theatres 'done in twelve parts, each part having twelve variations, each drawing was based on one of twelve patterns, the key to the whole. Each drawing had to be different; one might be groups of fishermen with nets, the other Ballet scenes or dancers'
