Loews Hotels chairman and New York Giants co-owner Jonathan Tisch could take up a new job as an auctioneer, if he had any spare time. Tisch raised $100,000 in just seven minutes as auctioneer for Lighthouse International, which fights vision loss, at the charity’s A Posh Affair gala Tuesday. His wife Lizzie, chair of the Friends of the Met’s Costume Institute, was honored at the Pierre Hotel dinner. Lizzie joked: “[I told Jon] they want to give me the Fashion Visionary Award and he said, ‘That is wonderful — is visionary code for consumer?’ ” Jon — who along with the Giants and Lizzie collected their Super Bowl rings last night — added, “I live in awe of her every day.” Also honored were architect Robert Couturier and Henri Bendel president Chris Fiore, who noted Bergdorf Goodman’s Linda Fargo picked up an award last year, and joked, “We’re just three blocks down on Fifth Avenue, so there’s a pattern here. We’ll know if that pattern comes true if Cardinal Dolan is standing here next year.”
