Hi -

Hmm, so it cracked around the reg hole and the corner is off.. I don't believe that kind of repair (minor painting, Mylar AF or archival film tape, etc.) would detract from the overall value, but obviously there is little you do to fix it since it looks like the cracks came from environmental stressors (maybe too cold, too dry, etc.). Definitely bag the thing in Mylar, backed with some paper/tissue; you can use archival tape to repair the damage; as for bends, there is a way to fix "crinkle"-type creases but I'm not about to get into that here... ^_-
