Photo Restoration. Before and After.

Here are two old photos taken around 1962, and suffered badly over time.
When you zoom in the damage of time is more evident. Took quite some time to restore.
Bringing back sharpness, I found difficult.
Here are the before and after. I have the owner's permission to post..
