Can we have a re-statement of the problem? As I recollect, it was "you land at at a totally unknown place on earth with NO instruments or tables, can you figure out where you are?"
I read that as "whatever you bring in your head and whatever you can construct out of locally available materials." To me, at least, that rules out baseball caps, credit cards, even tattoos.

Thanks.
One can wear it with a Bris sextant as a pendant on the neck:-)
Now we can discuss what to print on it:-)
First of all, Sun declination, equation of time
(or a beautiful anlemma instead), and refraction table.
Coordinates of the principal stars...
What else?
Lunar distance table for 2 years in the format of an XVIII century
almanac may fit conveniently...
Alex.
