Thanks guys. I've always said, rarity and paper deterioration are key to restoration. Can the poster be replaced by a better copy? Is it displayable as is? If the answer is no to both, then linenbacking is due. Otherwise, it is completely unnecessary in my opinion.
Also, I'd much rather buy a damaged poster and have the restoration done by someone like Mario or Dario, than buy an already linenbacked poster. I want to know what was wrong prior to linenbacking, what was replaced, what was added.
