Blueshirt

This still is from Lewis Klahr's 'The Pettitfogger, Collaging the Crime', which you can read more about here.  The image of the blueshirt floating over the bridge is to represent the travel of a rootless man.
I find it to be a rather haunting and depressing image: the deep blue of the shirt suggests manual labour and a sense of a enforced uniformity; the man unseen.
