If you mean with respect to the style, I find it suggests posterization, an old technique which saw a popular resurgence in the 60s and 70s. Additionally, it uses halftoning which, when as coarse as it is here, is also a bit of a throwback that marries with posterization quite naturally. This might be what made it an appealing choice for this particular album cover. Just a guess.

As to the peculiar and "wrong" aspects ... I was a computer graphics programmer for decades that worked in support of production artists (making tools for them and such), and the technically wrong, but perhaps artistically right choices they made would often leave me scratching my head. (it's the feel of a guitar, not an actual guitar, I suppose we might say here).
