Meshon - you could pull it into PS and use the clone tool and just add some edges to it.
add a bit to canvas, fill with white [on a layer below], then use the clone stamp tool [set to 60% opacity/50% flow] on the map layer and just add some of the paper texture to blend it to the white below.
I've done that before with one or two pieces. It will give you the edge space you want.
