This is a limited edition original T-shirt commemorating the retirement of Shinjiro Hiyama, former Hanshin Tigers player. It seems this T-shirt was only available to people connected to Hiyama and his friends, and I purchased it from a shop called RAT★RACE in Hyogo Prefecture. The size is M. I haven't worn it since I bought it, but there's a small white mark on the chest, possibly from rubbing against other clothes during storage. (See image 3.)
