Pokémon 151 marked a nostalgic return to Kanto's original roster, celebrating the franchise's enduring foundation. Released in 2023, this set arrived during a period of renewed collecting interest, offering modern production quality alongside classic subject matter. The set distinguished itself through special illustration rares—full-art treatments that reimagined beloved creatures with fresh artistic perspectives, drawing both longtime enthusiasts and newer collectors into the hobby. Squirtle's illustration rare showcases the iconic water-type starter in an artistic style that captures collectors' appreciation for character-driven imagery. As one of the original trio, Squirtle holds particular significance for fans, and the illustration rare treatment elevates it beyond standard releases. Collectors value these artistic interpretations for their visual appeal and their representation of how modern Pokémon cards honor the legacy of the earliest generations.
