What's interesting is that not one person of the dozens and dozens of people in the past few years, (merchants, FedEx, UPS or whoever) seem to give this pause or even remark. Then again, I'm not signing "important" big documents. So when I came into the office and coworker Jon brought the newly nominated Treasury Secretary Jacob Lew's signature to my attention, it interested me.
I wondered if perhaps he should just start being even more creative with his signature ~ might be interesting. Then I looked back on the list of signers of US Currency from 1861 to present and was impressed with the diversity.
