According to Brian Vaughan, the Y The Last Man wrap party tickets sold out speedily:

Well, never doubt the CBLDF, apparently. All 70 $100 VIP tickets sold out in about an hour this morning! Holy crap. Still, there will be some $25 “standing room only” tix available the day of the event, so bust out your tents and get in line today, True Believers! Just heard about some unbelievable “guest stars” who will be in attendance, and they should make all my fellow geeks’ heads explode.
