Heritage Auction has put another lot of 2 Black Star promo Pokémon Trading Card Game cards from Pokémon: The First Movie up for auction! 

These promotional cards were among the first few Pokémon TCG cards released for a public market in the West, alongside the aforementioned Dragonite and Mewtwo. While Pikachu, Mewtwo, and Dragonite each had featured roles in Pokémon: The First Movie, also known as Mewtwo Strikes Back!, Electabuzz had absolutely no screen time in the film, so its inclusion is rather a mystery to many. Furthermore, according to the lot's auction listing on Heritage Auctions' website:

The Black Star Promo series is comprised of 53 special promotional cards that were released from July 1999 through March 2003 and offered here are Electabuzz #2 with the following subgrades: centering 9.5, surface 9, corners 9, edges 9.5; and Pikachu #4 with the following subgrades: centering 9.5, surface 9.5, corners 8.5, edges 9. The artwork is done by Ken Sugimori.
