In the 1950s, Johns began using flags, targets and numbers as the basis of his paintings. These were ordinary familiar things, but also had an iconic, emblematic quality. This work is one of a series that he undertook in the summer of 1960, using the superimposed numbers 0 to 9. Johns let the process of painting the number sequence dictate the structure of the painting. This allowed him to concentrate on the qualities of the paint itself, exploring colour and thickness. The result is a highly abstract structure, but one rooted firmly in the real world.
