Mitchell & Ness

Mitchell & Ness, founded in Philadelphia in 1904, is known for its throwback jerseys, which sell for $100 to $400. It already has licensing deals with the National Basketball Association, the National Football League, Major League Baseball, Major League Soccer and several N.C.A.A. universities. The brand has changed hands several times, with Adidas acquiring it in 2007 and the private equity firm Juggernaut Capital Partners and Mr. Wulff buying it in 2016. It joins other nostalgia brands, like Reebok, that have brought in new owners with plans to bring new life into them.
