Amateur embossing is one of the toughest pressable defects to remove. Even if it is flat and flush, there are usually signs it was there, like stress lines from damaged fibers. I previously posted an Amazing Spider-Man #129, on that book the embossing came out 100%. On this Fantastic Four, the paper is nearly flattened 100% of the embossing, and in many places paper fiber damage is not visible. While this before and after is not a perfect example, it shows that Hero Restoration can give the book that extra needed to get the best grade bump possible.
