In 1997, Bandai released a beautiful line of cards, all drawn by the legendary Ken Sugimori. All of the Pokemon in this series were illustrated using one of their in-game moves and most of the artwork is exclusive to this series, so you won't see this beautiful art anywhere else.
The back of each card also has information on the Pokemon and usually shows their evolutionary line, as well.
I recently acquired a set on eBay and have 17 scans ready for viewing. I hope you enjoy this set as much as I do!
