last season the tigers wore memorial patches for owner mike ilitch (pizza pizza!) who passed away at the age of 87 in february, 2017. ilitch was a detroit native who started little caeser's and bought the tigers in 1992 from the owner of domino's pizza.
there was a white bordered version of the "mr. i" patch that the tigers wore on their right sleeves at home
ilitch also owned the detroit red wings, and they wore a rectangular "mr. i" patch
ilitch was also behind the detroit caesers softball team, and therefore the msa discs that were distributed in 1977
