Opinion on matching two different photos

Hi,
I am basically doing a job where I have to match heads of people in one series of pics, taken with a Canon digital camera and then superimpose them on pics of bodies, all originally taken from a 70s magazine.
It is all progressing well apart from the fact that I cannot seem to match up the ‘pattern’ that appears on the 70s pics onto the modern portrait shots. The pattern is like lots of dots or a moire effect, in other words a texture rather like when you scan a cheap magazine pic without de-screen.
I have tried the patch tool, but i am not getting a result that is good enough so I was wondering if anyone knew of a quick way I can make the two photos look texturally similar?
Many thanks in advance

Find a relatively flat area that contains the "moire" , select it, and define a pattern. Clean it up a bit with levels, and use the Offset filter to make it self-wrapping. You may get a clearer pattern from an individual channel, or from L channel of Lab or the K channel of CMYK.
Create a new layer over the un-patterned image, fill that layer with the pattern, and experiment with the best layer blend mode to superimpose it – probably lighten, darken, or screen. Experiment also with transparency, and the layer blending sliders.

Thankyou very much Mike… I am trying out ur advice right now.. Sounds pretty much bang-on what i need though!
will let you know how I progress in a short while
