Photo Restoration

So this week I took on a big challenge, I decided to restore an old family photo from 1933 of my great grandparents (on my dad's side). The original size of the image (barrel and all) is about 4" x 3". The image itself is about 2.5" x 1.75". My family is pretty sure they are at the World's Fair on Lake Michigan. The first image is the unrestored image and the latter is my restoration work.
