Here's the back - the pieces were dangling, which is why I chose this one as a restoration candidate. It is fairly easy to match the front mat, but the old mats are often created in layers, with a lighter layer of paper on the back. In the future I will probably practice adding the lighter layer. Also, don't attempt to do this unless you feel real comfortable with it. In most cases the glue, even if water-soluble, will not 'let go' of the paper enough to save the mount. That's good if all you are doing is soaking to clean the piece, but if you want the print removed you will probably have to slowly tear the mount away.
