Lo and behold: a question for nerds!

Hi!

First time forum user, long time Day[9] fan! 

Aaanyway.. What I'm here for is posters. Gaming posters more specifically. It's difficult not to notice all the awesome wall decoration Sean's got, and I wants me some of dem posters! I've been Googling, but this has yet to provide any proper results. I'm assuming some of his posters are from events he actually attended, but surely they're also available for purchase somewhere? Mainly looking for normal to large-sized posters, like his D3 and Ghost posters.

Regards,

Patrick aka 'Noirad'
