Curiously, one of the books I am in the midst of reading is Oliver Postgate's autobiography. It's Butterfly's copy, so I haven't been making much progress, as books seem to have a very hard time if I'm carrying them about (the train seems to be the only place I get to read books), and I don't want to put someone else's books through that.
It's an interesting memoir, and offers a few insights into his development as a writer.
