Very thin calculator in the form of a dollar note. This calculator
folds up to a very small package, and includes a notebook for
telephone numbers as well.
The picture on the right shows the calculator when folded. And yes, just in case anyone would in fact use this calculator as a $100 dollar note, there are the words SPECIMEN and VOID to make it clear that this calculator can not be used as currency. What a world...
