It's a double sided sleeve in a box with a window - very hard to explain somehow but works very well in the flesh. Talking of which - time for side 2?
Now we're using all sorts of artwork sources from different format sizes (from ex-rental VHS to posters) and then having to fit them into the window so as a result you end up having to decide whether you start altering the artwork to fit or present it unadulterated like we're going to do here for side 2...
