From the very day it was listed I've just been wondering when it finds its way here. And I'm really amused about the... questionable comments of all you guys who just want to get it cheap. I bet you won't.
Crappy picture, I do agree. But look at it exactly and you will see there is not, as it would seem at first sight, just a zone around the function keys which has not suffered yellowing. In fact there is no yellowing, but a crappy dark photo, and that lighter zone is just the original, light grey flip cardboard thing placed around the function keys, as can be seen here (not a photo of the keyboard on offer, but it shows exactly what I mean):

And one can see the coiled cable still has its plastic sleeve.
