This inverted map was created in 1955 for the benefit of tourists driving down to Florida from northern states.
Nearly all road maps point North. But we've found that many travelers turn their maps upside when going South. It helps them to know whether to turn right or left. Naturally its hard to read anything upside down.I'm old enough to remember the pleasure of driving with my family from Minnesota to Florida for spring break in the 1950s. As the map indicates, there were fewer cities and towns. My cousins lived in Naples, which is indicated on this map by an insignificant dot on the Gulf Coast. Florida had long stretches of two-lane highway traversing forest and scrubland and swamp with nary a subdivision in sight. Roadside stands sold oranges with a straw punched into them to drink from while driving. All the motels had neon lights (and no air conditioning). Many beaches were empty and their shell bounty unharvested. It was a different world.

Addendum: I got to thinking about that Florida trip quite a bit today, so after a quick search of my office I located a photograph from then. Herewith your faithful blogger with his sister, sitting on the back bumper of our family's Nash Ambassador, on an idyllic beach somewhere in Florida in 1956.
