These cards are produced as tickets/promotionals to a Star Trek
night at an Australian Disco. The backs have info about the night in question.
Many of them have a small ink marking, the initals of the person passing
them out. All the generations one I have seen have a mark. The size
of the scan for the movie Enterprise is misleading, they are the same
size. The difference is in color of the text and the back color as well.
If
you collect Trek Trading cards and would like more information on the
cards listed in this site, along with detailed checklists, images and
Trek card history, then check out the Card Collective CD ROM. For more
