This diptych is on two pieces of paper, and the photograph shows them side-by-side. However, when framing this piece, I think the pieces of paper could be framed side-by-side within the same frame, or framed separately, and either option would look great.
Each sheet of paper is signed, titled and dated on the back, and there is a note that each sheet is one half of a diptych. The paper is heavy-duty watercolor paper, almost as stiff as card-stock.
