Being somewhere in the middle, I thought I'd show mine. This is the very beginning of Songbird, which you can see on the cover says "Henry book," then "King's Creatures" and "King's Music," two of its early titles.
Songbird was started before I had a computer at home. I'm not sure if I even reliably had one at work, just things with some memory that I couldn't save personal stuff onto, which explains the second photo - a later portion of the book with handwritten, literal cut-and-tape inserts and lots of edits which wrap around the sides.
I thought my handwriting was bad then. There's no way I could draft a book by hand now, I'd never be able to read it.
