PS Sorry for the weird small patch of white light near the binding of page 4. I scanned that picture multiple times and I couldn't get rid of it.

Be sure to tag these as "Artbook". Also, you can go nuts with the resolution and file-size for these. It's unlikely anyone will ever scan these ever again, so these will be the only record of this existing in the coming decades. So make sure it's a good scan.
