This previously unfinished piece by 'Treas' can be found on the north wall of Port Adelaide's Port Authority Building.
It's finished now of course and there are plenty of examples of the final work but I really liked the feeling of the 'creative process at work' here.
My apologies Treas for adding a little of my own interpretation of 'unfinished' by removing the colour from the 'unfinished' side.
