World's Largest Map

Last year I searched around for the world's largest map. Well, here's a new entry into the category.

When this 130 by 166 foot plot of polished terrazzo tiling was inaugurated at New York’s 1964 World’s Fair, it was the largest map in the world. A facsimile extrapolation of a New York State road map by Rand McNally, the half-acre-sized piece of cartography today would still be the world’s largest map - if it had actually survived. But decades of human neglect and hard work by the elements have left their mark on the plywood tiles.

Kind of a sad story actually. I love the idea of it. Wouldn't a huge map of Minnesota be a hit at the State Fair?
