A mystery reveals itself slowly..

Last month I gave some thoughts on the 'jews for jesus' book that was sent to me anonymously.  Well they're starting to come out of the shadows. This month the book was followed with a letter that I've scanned in here. 

Yet there's still no mention of a group name or any contact information other than a PO Box in Austin.  Are they thinking that this is really going to be a surprise for us 'benefactors'?!?

One guy at my office that's a practicing jew has mentioned that some of his friends have mentioned receiving the book as well. Like I said, its their money I suppose!
