Anyway, Grandma didn't want to lose contact with any of her grandkids, and so in the weekly carbon-copied typed letter to all her children who lived away she started to include a picture letter for the grandkids. Looking at them now, I see evidence of tracing and carbon being used, or she would send a post card or colouring-in page (at one time there were six of us receiving them - how did a minister's wife find time without a little bit of cheating?).
They lasted from whenever she started doing them, up until we moved to Brisbane and were able to be in personal contact again. Sometimes she would include a story (often on the back) so my Mum would write it out on the page beside where she stuck it down.
I'm very glad that my Mum had the forethought to stick them into an exercise book, so that I have almost all of them. I don't think any of my cousins still have theirs, and this becomes a good way to share the riches around. My books became more special in December 1985 when my Grandma died suddenly with bleeding in her brain.
In some ways when I read them it's almost like reading a prehistoric blog.
The chance that they wouldn't be among the things I would grab in the event of house fire?
... Approximately None!
I should perhaps mention that their house had a railway line across the back fence and whenever we visited it was exciting to watch the trains go past (I believe she actually memorised the timetable so that she could get us in the right place at the right time to see them). I'm presuming this is why Grandma would have sent a photo of a sheep train to her horse-mad grandaughter.
