Qualifyer: I'm more into "photo-art" than I am restoration, but hopefully my .02 will get the ball rollin' on this.
For openers search
RP on keyword "moire" (show threads, not posts). For a boatload of more info Google:

====================
Is the blue cast intended?
In the example I...
* Desaturated to zap blue cast
* Used Levels adjustment layer to set white, black points (more overall contrast)
(Google:
photoshop levels set white black point)
* Merged visible layers onto a new layer
* Duplicated merged layer
* Applied Noise > Dust & Scratches (radius = 7)
* Lowered Opacity to 85%
Looks a little better to me, but...
Hope this helps.
