My wife's grandmother is a locally celebrated artist. She recently was forced to move to a retirement home and she has gifted us with several of her original works. They are mostly watercolor on some sort of high quality paper, along with a few Acrylic on Canvas.
While I doubt these works will ever become highly valuable like a Warhol or Dali, they are very beautiful and are incredibly meaningful to my wife and I. I would like to protect them and be able to pass them on to family in the future.
I plan to have them professionally matted and framed(probably at Michaels) but is there any thing I should do or have done to them first? I do not think that the artist did anything to preserve them.
