Right down to the signature
This signature was on a random business letter I received. To an American, this signature is very unusual. To a Kenyan, it's nothing out of the ordinary.
I had a discussion with a Kenyan friend about this. He theorized that people are taught to sign this way for security reasons - he said it's believed this sort of signature is harder to fake than a legible one. He then admitted that it's probably easier to fake, ironically. I dunno. Try forging Samson's.
