As many of us know, Mr Schwartz has used various spellings of his name and some very different signatures in the past. I found this on the Pranksters website.

I was surprised to find he is (was) a criminal lawyer so must have screwed up so many times in his past that only a parking company would accept him.
It's a fascinating read and goes to show how he has behaved in the past.
Enjoy
