Mary Theresa Keown has been working with the idea of Diptych, with oil on canvas, for years. You can see her work here. The piece above; ‘Mona’, is one of my favourites from her. A collage of sorts. Her ‘Constable’ piece is worth a look too.
Polaroids really do lend themselves to use in diptych. I do love it when it all comes together, like this. One must be careful, it can all go horribly wrong.
