The Sunday Challenge - Open Book

I'm afraid I've struggled a bit this week as we've had family staying meaning I've not had so much camera/computer time.

So not only am I late with this week's upload, but I've had to raid my archives to find something that I feel fits the theme of open.

This is the inside of an old book, which was given to me as a child. It was tied into the TV series of the same name, but you'll need to be of a certain age to remember it!
