This is a slightly comical example - it could be argued that there are three different potential “fronts” here. 
This is a Remastered Reissue. A cardboard slipcase over a clear jewel case with a big booklet inside.
To me, the REAL front here is the Slipcase as that is what I see on my desk in front of me.
Inside that Slipcase is the “front” of the normal jewel case, showing page one of the booklet.
And inside that booklet, we have an image on Page 3 which is the ORIGINAL cover of the original release. Or “Artist’s intent” of a front.
I see this as a “Boxset” with one item inside. The slipcase is a kind of open ended box with the real product inside. When we get a “Box \ Wrapper” image type it will be handy to better categorise items like this.
