Jack Antonoff wants to mail Bleachers fans... something?

Earlier today, Jack Antonoff extended an invitation to Bleachers fans to send a self-addressed and pre-paid/stamped envelope to a New Jersey address...

There's no word yet on what fans may receive in return for their efforts, but an Instagram post by Antonoff seems to suggest that fans may be mailed back a Bleachers patch.
