Pokémon Base Set launched the Trading Card Game phenomenon in 1999, establishing the hobby as we know it today. The shadowless printing, released before the "1st Edition" stamp appeared on cards, represents the earliest wave of distribution. These original printings are foundational to the hobby, capturing the moment when Pokémon cards transitioned from novelty to cultural force. Rattata, as card 61, appears in the common slot of Base Set. This humble rodent exemplifies the set's complete ecosystem—even the smallest creatures received full illustration treatment. Collectors value shadowless commons for their historical significance and nostalgic appeal, preserving a snapshot of 1999's explosion of Pokémon enthusiasm.
