I have a poster made from an actual picture at the WSOP I. All of the the entrants plus a few others are in it.
We have IDed all but one person in it.
No one seems to know who it is.

As far as the fly on the wall:
You don't have to be a fly, these guys will tell stories to anyone that will listen.
Slim is the best by far, Puggy runs a close 2nd, Chill Wills is 3rd.
