Restoration is color touch. It is subtly done and the book has a phenomenal appearance. Grade finally received, images to be posted ASAP.
Grader's notes:
Comic Description:
Incredible Hulk 181 11/74 Marvel Comics
Grader Notes:
light finger bends on cover
light spine stress lines to cover
small amount of color touch on spine
So basically things that a pressing would've taken care of, but CGC opted not to press and clean due to the color retouch.
