The Global Map is a neat toy from the 1940s. The whole thing is just under one by two feet in area, and consists of two rotating hemispheres that touch at a single point, with the purpose of showing the shortest distance by air or sea between two points—a quick and dirty way of showing a great-circle route with a bit of cardboard and no math. From the David Rumsey Map Collection. [Maps on the Web]

Mapping the Airways

mapping-the-airwaysOut this month from Amberley PublishingMapping the Airways. “Drawing on fascinating and unique material from the British Airways archive, curator Paul Jarvis focuses on the beautiful map artwork used over nearly 100 years of history to chart our voyages through the skies—from early adverts to twenty-first-century on-board moving maps—and the vital maps and charts used by pilots and navigators.” (The paperback edition seems to be delayed until June on the U.S. Amazon store, though you can still get the Kindle version.)  Here’s a short piece about the book in the trade journal Advance. [Tony Campbell]
