Help removing paper texture from 1970's photo

I am working on a gift for my parent's anniversary and need some help on removing the texture from this photo of my mom. Here's what I've tried so far without success:

1. FFT plugin (I'm new to this so there's a possibility I'm doing it wrong)

2. I also tried running a high pass filter on a duplicated layer, inverting it, then adjusting opacity. This gave me decent results but I lost a lot of the detail. To compensate for the detail loss, I duplicated the result (to preserve work progress) and tried erasing parts of the layer where the detail loss was most obvious to show the original image details. This works but then I'm back to the problem with the paper texture in those areas. (I know I could still blend better but I stopped at this point so I didn't exhaust myself before looking into other options.)

Any suggestions?

Thanks!
