The Ancient Mew Card is a the 8th Promo Card for Movie 1.
This card was released as a promotional card in the year 2000. It was given out with the purchase of a ticket for the theatrical run of The Power of One in the United States and other countries worldwide, limited to only the first week. After the first week of the theatrical run, attendees would only be able to receive a Moltres, Articuno, or Zapdos.
The Japanese version was included in the The Power of One movie pamphlet. Early Japanese prints of the card misspelled "Nintendo", in the understandable text, as "Nintedo", which was later corrected. Then, after the corrected version, a second version was released which features a new holofoil treatment with larger and more enhanced sparkles.
