Here's Hideo Kojima and Yumi Kikuchi holding fans of themselves, signed by themselves.
Everyone who plays a game at Konami's Tokyo Game Show booth gets a fan of some form. But these particular fans are being given out just one per day.
There are slightly less rare fans too, given out in units of 100 per day. See Famitsu.com's coverage of yesterday's Metal Gear Solid stage show for a look.
