Only 10,000 copies of the anthology were made, it was released in 1996 and contained the following:
all the games id Software made up to Quake. It also contains collectables, like a poster, comic, T-shirt, and a model cyberdemon.
Not that many exist these days certainly complete, but they do pop up on eBay from time to time.
btw the box is really cool :-)
