I have an article I did comparing black backs vs. red backs in this set with scans. This one appears to have been cropped. It is the only one that seems to have this issue. The sky in the top one (black back) looks thicker than on the lower red back version. You can see the item at the very top left mostly NOT there in the lower version. I also see that the small gap at the upper left is wider in the red back version. The dark color on the lower left is thicker in the red back version.
Why was this cropped and none of the others?
