Nat Geo does it again with an amazingly simple but powerful message to the humans of this Earth.

Just the tip: We’re only just beginning to clean up our act.

Ive always been a fan of the perfect bound yellow magazine. Perfect in so many ways. As much an icon of colour as the Yellow Pages or the red and black leather covers of Encyclopaedia Britannica with content and photography to rival any current affairs or travel pub out there. The size has always been a big appeal to me too, large enough to hold and read comfortably, but with a light paper stock, perfect to fold in half and store in your travel luggage at the airport - which is where I normally pick mine up.

Of course, many a copy of NG have been picked up at boot sales or charity shops - that’s the kind of following this treasured title has been recognised for if not only for the cover photo- any and every issue becomes a collectors item because of that . The latest issue is no different, and in some ways is more valuable than any other.
