Pokémon 151 marked a nostalgic return to Kanto in 2023, celebrating the original 151 Pokémon that defined the franchise's early years. This set arrived as collectors embraced retro aesthetics and first-generation creatures with renewed enthusiasm. The reverse holographic treatment became a signature feature of modern releases, offering an alternative to traditional full-art designs while maintaining visual appeal and collectibility. Squirtle, one of the original starter Pokémon, holds enduring appeal across generations of fans. Its appearance in 151 captures the character's charm through classic artwork, making it a core piece for set completion and starter Pokémon collections alike. Reverse holos of foundational creatures like Squirtle continue to attract both longtime collectors and newer enthusiasts building their collections.
