Had not noticed that! I trust Sue has and knows the answer? She's a walking talking encyclopedia on FF!

I had noticed the picture before, as to who it is, who knows. It would nice to think it's supposed to be Slugger in his Army days. I think most households have an old picture of a serving member of the family, and I suppose the FF family wouldn't be any different. It could also be the Colonel? It isn't clear enough to see the details, it could even be a First World War soldier, which would rule out both the Colonel and Slugger.
It is an interesting and intriguing query, though. I wonder if all the photos and postcards were props, or had some connections with the cast.
A walking/talking FF encyclopaedia, awww thanks for that, Anne.
