Overview
This is a double-hemisphere world map styled after the Dutch Golden Age of cartography, featuring celestial diagrams and ornate corner illustrations. It captures the transition from exploration to scientific observation, including the solar system and armillary spheres.
Story
Dutch mapmakers in the 1700s were the tech giants of their day, turning raw data from sailors into works of art. This design reflects a world where California was often still drawn as an island and the South Pole was a mystery.
Maker / Origin
The original map style is associated with the Keur family or Pieter Mortier, prominent Dutch publishers during a time when Amsterdam was the global center for map production. These families held monopolies on printing, making their maps status symbols for wealthy merchants.
Condition & Value
The map shows some rippling and minor foxing (brown spots), which may be intentional 'aging' or actual moisture exposure. The frame appears modern and in good condition. Significant fading from UV light would reduce the decorative value. Value is driven primarily by the decorative frame and size.
