Which means for the next few years, our money could be graced with a weird loop-de-loop. Or not.
The signature of the treasury secretary goes on every bill printed during his tenure. (The switch takes a few months.) Current Treasury Secretary Timothy Geithner came into office with a signature that was fairly abstract. But on currency, he managed to make his name legible, if less elegant.
What happened? NPR's Marketplace explained in an interview last year:
Kai Ryssdal: I gotta ask you about your handwriting. Is it true that this used to be your signature and you changed it into that chicken scratch? [...]
Geithner: Well, I think on the dollar bill I had to write something where people could read my name. That’s the rationale.
And Geithner explained why his script is not the best: "Well, I took handwriting in the third grade in New Delhi, India, so I probably did not get the best instruction on handwriting."
Where Lew learned to write in scribble-code, nobody knows.
