My grandparents in law

Hi!

Is my father in law birthday in a couple of days and I want to gift him with a picture of his parents. His father died in war when he was child. This is the only picture he has with his father.

Because I am thinking about printing it on a A4 paper I want the image to be enhanced and If is possible to colorize and placed next to each other (lady on the left site and the man on right).

I will tip. Thanks
