Remember when Lady Gaga threw a single Emporio Armani shoe into the audience at a concert at Paris’ Palais Omnisports de Bercy in 2010? (Yeah, neither do we.) Well it’s since resurfaced as part of the French auction house Drouot Richelieu’s “Man and his World” sale on Feb. 11 next year. The shoe is estimated to fetch between $5,000 and $6,500.
