As seen in multiple episodes of The X-Files

I traded a dude online for a few of these.

All in all, a very well made piece. I spent some time making my own version of these, but could never find a good reference for the FBI shield on the left hand side of the card. I was going to take a guess at what it looked like, and copy one of the more well known FBI crests. However, just as I was well underway into this project, an online pal offered these to me. I was very happy to accept, and they look great.

This is a picture of what is purported to be real cards used in the show. I swiped this picture from e-bay a while back when someone was auctioning them off. I don't know for sure if they're real, so take it for what it's worth.
