Topsun
1995 cards sold with chewing gum, even before the card game.
Published by Top Seika in 1995, before the Pokémon card game came out (1996), Topsun cards came with chewing gum, like this Pikachu 025. They exist in normal and shiny prism versions, with different coloured backs and variants with or without numbers.
Good to know They are among the very first Pokémon cards ever printed.
