Here are the two unnumbered cards (Takeshi Mori, 2000) inserted with the Vandread "Great Expectations" DVD. They promote the first season of "Vandread," a Japanese anime TV show that ran for two seasons (2000-2002). The shrinkwrap had a sticker that says "Includes Holographic Foil Cards." These cards have refractor foil (holofoil) fronts and they have the same regular card backs.

Both cards have the same tiny numbers on the front so they aren't card numbers. They might indicate that they were inserted together in the same DVD.

I don't know how many cards are in the set but I've seen at least 8 different ones.
