There´s a certain type of children´s literature that just positively requires a map at the end paper of the book. The map is there either to show an itinerary that is crucial to the story, or to enhance the ´piratesque´quality of the work – or both. This map is an example from a children´s book called ´Really, Miss Henderson´ from 1945. As you can see, the War had cost the lives of many, many good illustrators (unless this was an active attempt at creating a ´naive´-style map).I have never heard of the book, so if I had to surmise the story from this map alone, I´d guess that:
a group of British eccentrics (women and men, most of whom in the military) was shipwrecked in a small, isolated archipelago in the South Seas called the Pongawabu Islands.
One island is important because it has a freshwater well, but also dangerous because there are cannibals and at least one serpent – deadly, one supposes. This situation generates much of the tension and action in the story:
Major Crick and Miss Henderson are stuck on Cod Island, together with a rather large mouse. Imagine the hilarious and semi-romantic storylines one could come up with, using only these ingredients.
An unnamed island holds a cask of brandy and may thus be partially responsible for the sightings of mermaids by Colonel Farquhar, not to mention the flying pig.
On an outlying island, there is a case of sardines. The shipwreck survivors have to get over their differences and band together to obtain the food that will sustain them during their ordeal.
The lady in distress is very mysterious because of her immodest dress sense. She might be a native maiden, but then a very pale one. Surely,she can´t be English! Maybe she´s French?This map was found here at fulltable.com, a site that collects some interesting examples of end paper maps in books.
