I like the minimalistic design that is simple but at the same time not so abstract that the subject of the image is unclear. The colours of the type mesh nicely with the colours in the image and the curly typeface sets the mood for a calm day in New York Central Park.
The Central Park Entire, The Definitive Illustrated Map, locates thousands of different trees, showing precisely where each one grows in the Park, with a special icon denoting its species. There are over 19,600 trees on the map! $35
