I don`t think it would hurt a bit to touch up the frame !! Thats not where the value is on this one !! Even though not big bucks, they are unique !! I probably would not change the paper behind the silouette because that is the way the artist intended it so I would leave it as is,, even with a little damage !! If you decide that it is damaged enough to change it,, try to get as close to the original color as possible and be careful removing it as they sometimes adhere to the glass and will take off paint as well !! If it has stuck and doesn`t fall away easily,, better leave it !!
