Someone else on this thread knows more about this but it does in fact look like a photogravure (I don't know if this is the right term) rather than an actual photograph. If that is the case, they can certainly clean up the image at least a little bit and connect some of the the tears along with filling in some of the holes. Although you are missing entire pieces of the composite that cannot be restored you could always have someone take a very high resolution scan of the composite and do a double sided frame...one side being the original post restoration matted out properly to remove the missing players and the other side being the high resolution copy.

As a side note, I purchased the below Baltimore photograph composite several months ago. The photographs were cut out from N173's and while the entire composite could be cleaned up a bit the actual photographs would be quite a challenge. As a result, I put together my own composite and plan to have a double sided frame made up to showcase both the original and my own interpretation.
