In Honor of National Puzzle Day

Do you celebrate National Puzzle Day in January every year? If not, consider stopping by the Carnegie Museum beginning March 1 to enjoy Montgomery County and world history. The featured puzzle can teach which cities had populations of over 500,000 and which were the largest in the world during World War II.

There is a section about Allied Nations, Axis Powers, and an explanation of "Why Sea Lanes and Airways are Shown as Curved Lines."  The Gorman Company, Chicago, partnered with Mercator Projection to create this splendid puzzle. Mercator Projection was developed in 1569 by Gerardus Mercator as a navigation tool.
