The X-Files Collectible Card Game Deck Box

This 1997 sell sheet for the X-Files CCG (find at Amazon.com*) offers up another unreleased product from the line, but this time it is something I actually have in my game collection: A dedicated deck box for the game made of black plastic. My understanding is that the deck boxes were never released and the one I have is one of several the company made as demo boxes, so it is a bit special and is a fun and odd addition to my collection.
