As you can see, this one only uses one colour (yellow) plus red for country outlines. It's by far the prettier map, though. Lippincott cared more about making his maps look good than he cared about geographical importance. Minor coastal towns and geographical features get a mention if their presence makes the map visually more pleasing. Significant inland cities, such as Lille, Nuremburg and Leipzig, are omitted if their names would add clutter. Some cities in the Russian Empire, such as Reval (modern Talinn) appear to have been left out so as to convey an impression of vast emptiness.
Lippincott's maps are sought-after by minor-league collectors like me because they're so different to the rest and really are very easy on the eye. They're not inaccurate, just rather more impressionistic than the norm.
They also count Iceland as part of Europe, which as any player of Risk can tell you is definitely so.
