Being around for more than a century，the design of National Geographic，especially of the cover，has gone through many changes．The magazine is perhaps best known for its amazing photography﹣﹣yet it wasn't shaped until 1960s．It has also done a great job designing is famous yellow border．

•Seventeen．

The seventeen logo（标识）has stayed the same，but almost everything else about the design has changed．There was a time when the cover was simple．And then things just got more and more cluttered（杂乱）．The magazine cover's job is to sell the magazine﹣﹣it has to stand out from the others．So the design starts to get louder and louder．But honestly，you might get a bit of a headache when you look at the seventeenth covers for too long．
