Provenance

Where it came from

The Koffing card was released in 1999 as part of the initial Base Set of the Pokémon Trading Card Game, which debuted in English following the massive success of the Nintendo Game Boy titles. Designed by Ken Sugimori, the card served as an introduction to the Poison-type mechanics within the game, with the artwork reflecting the original sprite aesthetic that defined the franchise's early visual identity.

Sugimori, the primary character designer for the Pokémon series, created these early illustrations with a focus on simplicity and accessibility to mirror the straightforward gameplay of the first generation. As a common card, the Koffing was widely circulated and remains a nostalgic touchstone for collectors, representing the foundational era of the hobby before the game's mechanics and card design complexity evolved in later expansions.
