You can do what I sometimes do: buy the download, then make your own box! Luckily scans of his boxart are pretty easy to find (in fact,
here ya go!). If you have a print shop nearby, like an Office Depot, you can have him printed out on good paper that better mimics official boxart; it'll be around 10.2" x 7.2" to properly fit in a DVD box (and you can get a DVD box from anywhere; just find a cheap DVD from a garage sale or Walmart or something, take out the slip, and put your own in there).
Best of luck to you!!
