Oil on canvas, stretched and ready to hang.

This 1960s Newcastle geographical map for coal was the perfect spot for a Black Cockatoo that I've called Coal Face. Edges turned with the map where possible, otherwise painted white. As this is a 60 year old large paper which has had a previous life and was never meant to have someone glue it onto a canvas, let alone paint on it, there are signs of its former life. I like that.
