Who, What, When, Why or how? Yours?
15 years ago I adopted a client’s usage of spiral bound, college spaced, Mead 5 Star (Very durable) note books to take notes, outline projects, agreements, conversations, etc. All chronological. I’m on #36.
There’s a few pages I’d have to work on to decipher but your pic is undecipherable so its yours as an example or that of a famous killer? Inquiring minds and all that?
