Dominus of Exult managed to get his hands on a very cool and rare collectible, the promotional prepaid telephone card for Wing Commander Prophecy! It came in a large folder covered in key art, which contains a smaller container for the card itself. The denomination was 6 Deutsche Marks. To explain to kids of the new millennium: prepaid phone cards were used in the '90s to authorize calls from a pay phone without having to carry money. This is one of at least four similar Wing Commander promos that we know of. One was released in the UK with the Wing Commander II logo, another was available in Japan with the Super Famicon WC artwork and a second Japanese card tied in with the Wing Commander Movie.
