Auction on main City site

Okay, shoot me down if this has been posted on here before, but I was just on the CCFC website, looking at the new kit, when I spotted a tab marked 'auction'. I clicked on it, and it looks like the club has been auctioning off a couple of shirts and mugs, signed by our boy Aaron Ramsey. The home shirt went for over £1000, which is pretty astonishing.
Not sure how I missed this, or how many people were aware of it, but I'm guessing it was some sort of charity thing? Anyone know anything?
