Yeah, that's definitely _not_ a moire pattern due to scanning. Glue dots in a self-adhesive photo album is my guess. What makes them hard to cope with is that they are exactly the same scale as the details in about the faces of the subjects. That makes them harder to deal with since the blur radius then eats the face details, and unsharp mask won't bring those back. Usually a moire is at a higher frequency than the photo details, so a small radius blur and then an unsharp mask usually work pretty well if a re-scan's not possible.

So long as the face areas stay 'sharp' (as possible they're none to sharp to start with) the eye is pretty forgiving about blurring in the remainder of the photo. There's no magic bullet for this one.
