When I was in the Netherlands a couple of weeks ago I bought a reproduction of an old map of Haarlem.
In the Haarlem History Museum I found the Kaart van Nautz. The map by Mr. Nautz dates from 1829 and shows the city as it was in 1822.
We had the poster dry mounted by a shop in Durham's Main Street and the result is great. The map is free of wrinkles and very easy to place on the wall.

The map is dry mounted against a hard surface, which makes it virtually wrinkle free and very easy to hang nicely on the wall.

On its place, near the dining table. I want to replace the wall mount with something invisible, I don't like the plastic and nail just above the map too much.
