This card was included as a bonus with sweets from Meiji Seika, which were sold around the time of the release of the Pokémon Gold and Silver series. The "Pokémon Get Card" is characterized by its gold hologram finish on the front. Chikorita is one of the three Pokémon you can choose from at the beginning of Pokémon Gold, Silver, and Crystal versions (Grass type). The "40" written on the image is likely the card's serial number.
