It is strange how things turn out. This piece of A3 paper was collaged with squares of newspaper. The newspaper had been used to clean a stencil after it had been rollered with white acrylic paint. I added a coating of walnut ink when I got it home.
Upon looking at it again I realised it reminded me of the photograph below of a manhole cover over a cellar in Malvern which I took some time ago when a friend was visiting.
