The reason it is a historic post is not because it's a great post, its a historic post because it is a history of the MapQuest® logo.
The original MapQuest® logo to the best of our knowledge is the red worded MapQuest®
pictured below, and accredited to Wikipedia ( http://en.m.wikipedia.org/wiki/MapQuest ).
We don't know what the font is called but it looks stone age or Flintstonian. (I think we just made up a new word in the English language, "Flintstonian"- definition - of or pertaining to the Flintstones.)
The other three green logos are the current logos that MapQuest utilizes today.
