Soho's landmark Puck Building was packed last night as the Bailey House held its 20th Annual Auction & Party.

Designers Jonathan Adler, Simon Doonan and John Bartlett, architect Jeffery Povero and Project Runway's Tim Gunn hosted the event which included both a silent and a more lively, live auction. Two women bid top dollar for a lunch with CNN's Anderson Cooper: $4,500! The following item: a maple leaf Mapplethorpe went for $9,500.

ABC News SVP Jeffrey Schneider, chairman of the board of Bailey House, was also the chief seer of paddles during the live auction, not missing a bid. By the end of the night $800,000 had been raised.

Among the 850 guests, the aforementioned Cooper (pre-AC360), GMA Weekend anchor Bill Weir and WABC's Bill Ritter.

Now going on 25 years, Bailey House provides housing and other vital needs to people living with HIV/AIDS and to their loved ones.
