Grandpa and family

I'm searching my grandfathers chest for old photographs.
Because he was one of the first photographers in Iceland? (Born 1873)
No, because a very brave man have published the first volume of a book about the people that built Reykjavik and needs pictures.
My mother is the little girl the pen points to on the picture.
I think I tore this picture in two when I was very young and helping my mother to clean the cellar. Saw only the back of it and was going to use it to sweep up dust. Now I have to make amend for what I did and scan this picture into my computer and fix it in Photoshop and send to the brave man.
It always bites you in the ass, doesn't it?
