Mac, I have had varying degrees of success with photo restorations. Some I consider a great improvement, some a wasted effort. I do this as a hobby only.
This particular pic was in pretty good shape when I got it. I mostly had to work with the background. The frame is not original, it is one I use to display these old photos on the internet.
If you will email me a scan of the pic you want restored I will give it a shot. Of course there is no charge and you aren't obligated to even keep it. Who knows, we might get lucky.
P.S. ___ There is of course always the option of professional photo restoration but let's see what we can do first.
