Poster Mog mentioned this is the v. 36 cover post I recently made. Before the forum went down I briefly mentioned this but no sooner did I make note of it then the board went the way of the Dodo.
I was going to chalk it up to my imagination until Mog said:
Also, my nephew told me he thought the paper quality was slightly different… Any truth to this?
I noticed the same thing. The paper would appear to be a higher stock and also slightly more white. This is interesting. Perhaps a result of the recent victory for copyrights and manga campaign.
