On Wednesday night, style magazine-cum-retail venture Monocle hosted a soirée at the Gramercy Park Hotel for a chic set including Jenna Lyons, Chace Crawford, and (naturally) Monocle’s Tyler Brule. But another guest made an appearance at the party…mysteriously enough. None of the girls working at the door saw him come in, but later in the night, David Blaine appeared and entertained Brule with card tricks.
