You could get the picture colorized and framed. Did you get the opportunity to meet your maternal grandad even though your father's father passed on so young? Thanks for sharing the picture. Sorry about your loss. In 1952 being widow must have been rough for your grandmother. I have a feeling that she was very resilient and that stays in the family for generations! Frame the photograph, preserve it and it may it cultivate a stronger sense of identity for your kids.
Sadly I never knew my Grandad. I will be cherishing the photograph for the rest of my life. Stephen
