Scanned image from 1970's era textured paper question

I have a color photo from the 1970's that was printed on a textured paper that
was popular at the time, it had a grid-like texture.
Does anyone have any ideas how to improve a picture scanned from this type of paper?
One thought I had was that a 2D FFT might reveal the spacial frequencies of the paper
grid and could be used to minimize it.
Any other ideas on this?
Thanks!

Can you post a cropped version of the image?
Saw this suggestion on the web:
Textured paper can come out as harsh and unappealing on the scan because of the bright light the device uses. To solve this issue, you have to scan your artwork twice, rotating it 180 degrees, and then use Photoshop or other similar software to unite the two
Another suggestion was to photograph the print using diffuse light which will minimize the texture.

I was thinking that trying to overlay two images/scans rotated by 180 deg it would probably require multipoint warping/registration after rotation. PWP7 can do it, but I'm not sure how to do it in PWP8.

If you use a scanner, two point alignment (shift/rotate) should be all you need.

OK, I cheated on this. I've seen so much hype on AI assisted processing, I decided to try a online trial.
The results are amazing. The artifacts (JPEG and paper texture) are gone. Things like
our hair (fine detail) lo0k great - not over emphasized, but nice.
I'd upload an image, but I don't see a way here that does not require some sort of URL .
In general, I'm not a fan of the types of fakery that AI can encourage. However.. for fixing this
snapshot from the days of dating my wife, it was amazing.

Hi John,
I'm curious to know which AI product you used. Also, if you click on the 'attachments' tab (below the topic text entry box) you can insert images to your topic entry (600 KB size limit).
Thanks
Mark

Could you post your input and output images and the name of the image processor ?
