From the reference box #16
"Tour Holland by motor car" is a wonderful 1950's leaflet about touring this 'land of broad horizons'. It gives you the legal requirements for driving in their country, a low down of the road signs, a brief highway code, parking & car washing charges, touring routes, hotel & tourist information contacts and best of all it opens out into a map of the countries 2 main roads, in a kind of tube map style.
The map shows the towns and villages like tube stops along a simplified road and has places of interest; windmills, galleries, museums etc... marked on with simple icons. It's a superb piece of design and still looks really modern over 50 years later - the true test of good design!
