When you bought a Lisa, not only did you get a box full of manuals, but also, the keyboard itself had a small pull out set of two sided indexed vinyl cards with hints. Apple was also nice enough to put these on vinyl (or some other plastic), and also provided space on the back for taking notes in pencil. Presumably the notes could be wiped with a wet sponge, or erased.
Here they are! (I unfortunatly have two Lisa's that were thrown out, so I've no documentation for them, however, one of the keyboards had the hints inside of it, and I've scanned them for your enjoyment!
Be careful, as these are rather gigantic JPG images.
