The assembled map. It would take some more adjustment and warping as the Nubble Light image was added. I played with the Layer Effects, settling on layering the map over the image and adding the Color Burn effect. I had to erase some of the map to bring out some of the lighthouse image. I copied the lighthouse keepers building and pasted it on top.
I then selected the Nubble Light image with a feathered oval and deleted the periphery, squaring the sides to match and changing the border to white.
