Jack Lew's Loopy Signature Gets a Makeover

Treasury Secretary Jack Lew's infamous loopty Lew signature appears to be undergoing a much-needed makeover.

Lew's illegible slinky-like signature, which will one day grace every U.S. dollar, came under intense scrutiny when President Obama nominated him to lead the Treasury Department.

"I had never noticed Jack's signature, and when this was highlighted yesterday in the press, I considered rescinding my offer to appoint him," Obama joked when he announced Lew's nomination. "Jack assures me that he is going to work to make at least one letter legible in order not to debase our currency."

Now that he's been in the job for a little more than two months, Lew appears to be working on his John Hancock. A government document, which he signed last week, shows a far more legible signature.

Lew would not be the first Treasury secretary to enhance his signature. Timothy Geithner and John Snow both worked on their penmanship before autographing the dollar.
