Mick Jagger was a New York culture vulture over the weekend. After visiting a preview of Bob Dylan’s paintings at Gagosian Gallery, the Stones legend and SuperHeavy singer hit the rare- book room at the Strand near Union Square. Flanked by gal pal L’Wren Scott and two bodyguards, Jagger spent an hour browsing, according to spies. He bought “a stack of antiquarian and rare” tomes on painters Egon Schiele and Marc Chagall, graphic designers Merle Armitage and Alex Steinweiss, fashion designer Madeleine Vionnet and photographer Helmut Newton. Jagger also left some room for fun, buying a first edition of Ian Fleming’s “On Her Majesty’s Secret Service.”
