The "Mew" card released exclusively at the Next Generation World Hobby Fair (WHF) is highly sought after and prized for its rarity among collectors of Pokémon cards (specifically the "Old Back" or original design series). This promotional card (LV.25) was included in the "Special Limited Expansion Sheet," which was sold exclusively at the Next Generation World Hobby Fair venue in December 1997. Although the sheet originally sold for just 100 yen (96 yen), its value has skyrocketed today due to its mystical artwork and limited circulation. Its scarcity is extreme; because it was never included in standard booster packs and was distributed or sold only at the 1997 event, very few copies exist on the market. Pristine examples are difficult to find because the card was originally attached to a backing sheet, requiring users to peel it off by hand. Consequently, many cards suffered corner damage during removal or were worn out from use in battles by children at the time, making flawless, undamaged cards exceptionally rare. The card also captivates collectors with its artistic merit, featuring a charming and mystical illustration by official Pokémon designer Ken Sugimori; it depicts Mew emerging from the darkness, enveloped in a soft, ethereal glow. ※ There are chips or creases on the corners of the card. ※ As the photos are taken by an amateur, they may not perfectly capture the card's condition. Please refrain from bidding if you cannot accept imperfections not visible in the photos—such as edge whitening, scratches, peeling, creases, bends, or dents—or if you are seeking a flawless, mint-condition item. Since these are cards from decades ago, they may have factory-origin flaws or signs of aging (such as discoloration); please examine the photos carefully.
