The developers of the forthcoming Uncharted 3 game attended one of the recent AMC Uncharted 3 events. At that event, one lucky fan won an Uncharted 3 poster which was created by Michael Krahulik (AKA Jonathan “Gabe” Gabriel) of Penny Arcade fame.
The poster in an of itself is quite nice and will actually be available to anyone that pre-orders Uncharted 3 via Gamestop.
The poster that the fan won, however, was hand signed by a slew of Naughty Dog staff members.
Info on the poster directly from Penny Arcade can be found here.
