Columbia University sent me this handy little calendar/ruler card. On the flip side I discovered the KEY TO NEW YORK. I was not aware that such a key existed. However, under closer examination, I found this key to be one of the more confusing systems I’ve ever encountered:
"To find the location of a number on the following Avenues of Manhattan, cancel the last figure of the number, divide the remainder by 2 and add or subtract the given key number." WTF?!
It was a lovely peek into a world before GPS and Google Maps, when an address like 934 Third Avenue could really ruin your day if you were not sure exactly where it was before you set off on your journey. I suspect many strange keys like this existed in the predigital world, where the exceptions were almost as lengthy as the system itself. What a world this was: men applied pomade, women danced the mashed potato, all the while their heads filled with complicated Keys, Shortcuts, & Acrostics designed to help them navigate the universe.
On a related note: If the exceptions outnumber the applications, is it still a system?
