Any attempt, whether professional or amateur, to enhance the appearance of an aging or damaged comic book using additive procedures. These procedures may include any or all of the following techniques: recoloring, adding missing paper, trimming, re-glossing, reinforcement, glue, etc. Amateur work can lower the value of a book, and even professional restoration has now gained a negative aura in the modern marketplace from some quarters. In all cases a restored book can never be worth the same as an unrestored book in the same condition. There is no consensus on the inclusion of pressing, non-aqueous cleaning, tape removal and in some cases staple replacement in this definition. Until such time as there is consensus, we encourage continued debate and interaction among all interested parties and reflection upon the standards in other hobbies and art forms.
