That said, I didn't see the other two posters there, and the vast majority of the stuff is 1080p. That resolution wouldn't work as a wallpaper for my monitor's resolution, let alone be useful for printing at poster size. Still, a nice collection of stuff in once place.
Yeah, my bad, that was a wallpaper collection.
It's actually quite easy to find most of SC's high res art, concept and otherwise, by simply googling something like 'star citizen artwork' or 'star citizen poster' and setting the picture size filter to 8 million pixels and more (you could get away with less for smaller prints, I suppose). You can find pretty much all the poster art you can see in the background on AtV and what they have hanging on the walls in the Frankfurt office, plus a ton more. It pays to download and compare images from different sites / sources, as some of them have been uploaded to imgur & co. and have received dat compression treatment. Not that some of the originals don't suffer from jpeg compression as well. I guess they're keeping the 'good stuff' for when they decide to sell prints themselves. Gotta fund fast.
I'll definitely get a couple printed in the coming weeks and report back, once I decide what to go for and how to frame and / or canvas the prints.
