Despite their immense popularity and longevity (the team has existed since 1936), the Hanshin Tigers have only been Central League champions five times, winning the Japan Series only once. This card set honors that single victory.
Each box comes with 52 cards. The seven extra cards include five parallels and two autographs. The parallels only have border color changes; black is not serial-numbered, while gold is numbered to 45 copies each.
