The card is in English and manufactured by The Pokmon Company in the United States, with illustrations by Shiburingaru

Many Pokmon TCG fans who collect Master Sets also include every promo card from every product branded with the set's name, but on there are other collectors who instead treat an era's Black Star Promos like its own numbered set (which it is, as you can tell from the numbers on the bottom of the card) and thus collect it into its own separate binder
Despite early $30 sales for Wan Shi Tong being recorded, it feels like that price point is far behind us
