Oil on paper, ready to hang.
Signed on the back.
I'm no longer working on very small strip maps, so you'll find that any new work is this size or larger. Most of my vintage maps are Australian military survey ones, or similar, usually from the 1960s to 80s. I've wrapped the map around the edges of the canvas. Ready to hang or be sent to the framers if you choose to be put in a timber box frame. Lightly varnished for protection.
