The images you'll find here have been greatly shrunk and compressed, for the sake of travelling over the internet. If, for some reason, you'd like a higher quality scan, I do have that available and I'd be willing to share. What I'm willing to give you is only limited by the medium of transfer; the file sizes of the raw scans range from 10MB(jpeg) to over 85MB(png) and you can't upload pic sizes like that just anywhere. Oh and each poster contains 3 raw scans.
The point is, if you want something higher quality, talk to me and we'll figure something out. (comment on an image, ask in the guild lounge, pm me, anything)
