Guess it would be all hand work restoration.

Would any of you have any suggestions on how to go about restoring these images?

I'm scanning two old magazines that were printed using a 'spirit duplicator', better known as a 'ditto machine'. The magazines are overall well preserved, but have faded badly in some parts, and some of my scans are coming out looking like this:

I played with them for a bit (not very carefully), and here is what I would suggest.

1. Reduce the noise in the images (using something like filters->enhance->despeckle)
2. Try to sharpen it a little because this usually ends up slightly blurred (using something like filters->enhance->unsharp mask) You need to play with steps 1 and 2 until you get something you're happy with.
3. I then tried to convert the image to a vector format, and I used autotrace for this. Here [
