What is unique about this map? Being able to think clearly and accurately about our planet-wide interconnectedness has never been more important. A Cahill-Keyes world map makes that easier. Other world maps have their own attractions, but are well-known for their distortions. Cahill-Keyes is a great map to help you understand those distortions and avoid making misleading assumptions about the world as a whole.

Continuing Cahill's goal: ... to accustom the sub-conscious mind of the next generation to a planetary rather than the parochial outlook and its intolerant arrogance, which today, in many lands, so threatens the peace of the world. —1939

From the family of B.J.S. Cahill:

This map has received kind support from the family of B.J.S. Cahill: As descendents of the inventor of the "Butterfly Map" we think it is wonderful that Gene Keyes has worked so hard to bring it to life in such a dramatic new version. The Cahill-Keyes map represents a significant milestone in cartography and we celebrate its availability as a poster to cartographers, map enthusiasts and the world at large.

Specifications: The dimensions of this 1:27 million World Political Wall Map are 1,560 mm x 750 mm [61" x 29"]. The map is lithographically printed at high resolution. The paper is poster weight (170gsm) and will benefit from mounting on Gatorboard or similar.
