These were one-per store and contain some really cool information from that era of gaming. It also has Sony contact and support info, and a lot of waxy and nicely produced one-sheets for a lot of PSOne era games, including some from higher tier publishers (image below). I can only imagine that there aren't many of these left lying around at one per store in conjunction with the fact that this was industry material and not intended for consumption.

Asking $325 shipped as this is probably the only example you'll ever see. Obviously this will more likely be appealing to the hard core apocrypha collectors more than the general game stacker.
