Participants were required to mail a flyer included with copies of Trade Please by Suzukisan to MediaFactory along with any two Pokémon trading cards and a return envelope within the campaign period. Participants could select a "course" detailed on the flyer by writing in the appropriate space. The "A Course" included a Charizard card and a Trade Please! promotional card. The "B Course" included a copy of this card and the Trade Please! card. The "C Course" included a Venusaur card and the Trade Please! card. MediaFactory would then send the two cards from the chosen course to the participant, completing the trade. This print was later reprinted in the Intro Pack and again as part of the Pokémon Song Best Collection CD. The original Base Set print was later reprinted in the Base Set 2 expansion.

In Mysterious Treasures, an almost-identical Chansey card was released; however, due to the HP, weakness, resistance, Retreat Cost and self-infliction from Double-edge varying, it cannot be considered a reprint.
