Vintage IU Hoosiers Bison Mascot HoodieIndiana has experimented with a handful of mascots throughout its storied history. Starting in the late 60s, the school featured a bison as its mascot for about a decade. Around that time, this guy started showing up on some promotional materials and even decals. We think he looks more like a bull, but we love him anyway. Products are mocked up on a size S. Graphics may appear smaller on larger sizes.
