I mentioned in a previous post that NTT switched to the barcode backs on their telephone cards in 1991. Before 1991, each back had a unique numbered back for easy cataloguing. After 1991, they went to a generic back with a standard barcode number making cataloguing that much more difficult. Here is one of the first barcode backs (The dreaded 955595 100160 <110-016> number)....which happens to be the great Yokozuna Chiyonofuji. He was called the "Wolf" because of his cunning in the ring and his superb physique was popular among the fans. Chiyonofuji is regarded by some as the greatest wrestler in history due to his contributions to the sport on and off the dohyo. My goal is to start cataloguing Japanese sumo telephone cards with earnest in 2019....as Fuji would say "Down the Rabbit Hole."
