Do I need to disclose comic book alterations before a sale?

Mark Zaid (Owner of Esquire Comics) gives expert video advice on: How does restoration affect a comic book's price?; Should I use tape to repair my comic books?; What is comic book 'color touching'? and more...

From an ethical standpoint, certainly in my perspective, and it's coming as one who is an attorney as well, disclosure of anything done to a comic book that would significantly impact the value or create a decision where you, if you were the buyer you would want to have the ability to render an informed decision, should be disclosed. All forms of restoration should always be disclosed. Then you get into the grey areas, such as pressing. There are organizations, such as the Network of Disclosure which I helped found, which advocates that all types of treatment should be disclosed. The meaning, or the reason for it, is to allow the buyers to render an informed decision. If that decision is to purchase, for example, a pressed comic book or a colour-touched comic book that's fine. If you want to pay full price that's fine, and if you want to pay half price it's still fine. But the issue is from an ethical standpoint to disclose treatments so that the buyer doesn't have remorse when they find out a day, a week, or a year later that something happened to that comic book that they weren't aware of at the time.
