• Poster Pokémon 30th Anniversary Poster Collection Booster Box English Collection Booster Box from the Pokémon 30th Anniversary. • It’s an amazing product, you get 3 boosters packs, 3 promos of the legendary birds and the poster from this unique and very rare collection! • New, Sealed. • English. In my opinion is the best language of the set because the cards are more valuable and literally all products are sold out.
