I recently purchased a used copy it the wheel building book by Jobst Brandt, and inside there was a bookmark with writing on it. It was from a grandfather with loving words to his grandson, of encouragement. Essentially to keep going and not give up. There was more too. I imagine that those words were comforting to the receiver, as well they were to me. I'm keeping that bookmark. (Of course they could have just been words of encouragement to a frustrated apprentice wheel builder).

Thats an interesting find. I would definitely keep that - maybe frame it, and if you have or could find one of those Derailleurs you could mount the two in a curio box for display in your bike cave.
