This Japanese Pokémon TCG Trainer card, Imposter Oak’s Revenge, is from the original 1997 Team Rocket expansion (known in Japan as Rocket Gang). The illustration by Ken Sugimori shows a wily Imposter Professor Oak with Team Rocket’s Koffing and Gengar lurking behind, all framed by the card’s signature silver border and accented by the gold “TRAINER” banner. The card’s vintage design and prominent Team Rocket “R” logo emphasize the villainous theme and classic late-’90s aesthetic of the Pokémon TCG. Collectors prize this rare card for its nostalgic artwork and its place in early Pokémon trading card game history.
