Fans of Eminem can rejoice! It’s been almost two years since Em came out with Recovery, and some were starting to think he’d slipped back into hiding again. Apparently, he was just waiting for the World Series to be over.

It was this past weekend that Em added a special edition Marshall Mathers baseball hat to his online store. Typically this wouldn’t be news, as Eminem’s been running the clothing label Shady Limited for the past several years. But this hat was special. Not just because it’s fashioned in iconic Detroit Tigers style, but because it’s got clues of a new album coming from Em himself.

The hat is extremely similar to the hat the Tigers where, Em’s hometown baseball team. On the front instead of the Tigers “D” logo, Em has placed a backwards “E” to represent his own name. But it’s not what’s on the front that fans will be interested in — it’s the side panel!

Here Em has inscribed all the years that he came out with a solo album. It begins with Infinite in 1996 and goes all the way until 2010 to represent Recovery. But there’s one more date there. Underneath his last released solo album date stands the year “2013,” leading many to guess (correctly, we assume) that Em will have a new album due out next year.

The hat is currently on sale at Em’s online store. The hat sells for $30 and the description on the site reads, “in honor of the big games and the hometown team’s return to The D.” A portion of the proceeds will go to The Marshall Mathers Foundation, an organization that helps disadvantaged youth in Michigan, Em’s home state.
