Anyone have a Metro:LL poster that DOESN'T have all the platform logos and such on it? The ones that were given away in contest etc. just have a picture of the tunnel, and light shinning down with Artyom looking up. I'll PayPal someone if they have one, since I would really like one. The posters with all the logos on it don't appeal to me. I loved the game so much it needs to be commemorated in my office.
try pm'ing professor pew and see if he can provide a high res image and then have it printed at a professional printing press, only if you get stuck
You could always just get some high quality printing paper, find a high resolution image of Last Light that you like and print it out. Sure, you'll always be limited to just A4 size (unless you have the tools for larger sizes), but then you'll have the exact poster you want and you could also make different types.
