This is a new issue entirely, and I cannot see how it could be done outside of CGC.
This is a 1.2 million dollar book we are talking about. It was carefully doctored, by a very high level restorer. The tear repair is visible but very tight, and the color touch is obvious only when comparison is done side by side.
The biggest issue to me is that not only did it bump from 9.0 to 9.4 after restoration, but it was certified as part of the Windy City pedigree as well. This would have to be very high level inside actors to do this.
