I noticed nobody seemed to have done a visual library of the OXM demo case covers which makes it extremely hard for anyone collecting them, so I did it.
You can find all 61 covers (although I hear rumours of a 62nd)
You can download them in batches of 10 covers
Hopefully helps a collector with searches or will let you print off a temp cover
You can check it out here hopefully it helps someone who's an Xbox fan out
