I used to have Esprit as original (some years ago).
The back of the packaging said something like this:
"This box includes a disk, some instant coffee (!) and NO manual."
So there was no manual for this game, it was pretty easy to figure out anyways. But there was something else in the box, kinda hard to describe actually... it was something to be used with the code protection that appears somewhere in the higher levels (I think it was somewhere around level 70, and only appears once). It was something you could fold and bend, made out of thin cardboard. Actually pretty tiny, maybe 5 centimeters wide and 3 cm high and flat.
