Here the mapmaker is at last on home ground, and it shows: Blaeu's Europe is dense, assured, and proud, its borders crowned with views of London, Paris, Rome, and Amsterdam and figures of the continent's nobility in their finery. This was the Europe that was busy mapping — and claiming — the rest of the world, drawn by the city that had become the mapmaking capital of the Earth. The fourth quarter of the classic four-continent set, and its confident centre of gravity.

Before a size goes on sale, the file is measured against it: pixels per inch at that size, how much of the picture a crop would lose, tone and sharpness. A size that fails is not offered, so there is nothing to choose wrong.
