Throughout the years 1997-2006, the official Pokémon publishing company Shogakukan released many promotional stamp sheets. They could not be used as actual postage stamps, but were meant for collecting. 

These stamps had beautiful artworks ranging from classic Ken Sugimori designs to nostalgic 3D images from your favourite chilhood games. Their distribution varied from special events to being inserts in magazines or even inclusion in packs of bubble gum. They are amazing collectibles

This is one of the very 1st promo file collections this is complete and showcases some special fire water green sets and special edtions jiggypuff etc
