Eminem has teased the release of his next studio album via a commemorative baseball cap.

NME reports that the Detroit rapper is selling the 'Eminem Baseball Tribute Champ Hat' that lists the years of "landmark Eminem solo albums" on its side panel. The dates are 1996, 1999, 2000, 2002, 2004, 2009, 2010 and 2013.
