Slick Rick ‎– The Ruler's Back

Does anyone know what type of inner sleeve this should have?
Is it plain or an inlay?

I have a copy of this. This 2LP unofficial release contains the much sought after ''It's A Boy'' Large Professor remix originally only available on 12'' along with the S.I.D remix of Mistakes Of A Woman In Love With Other Men. A more complete version than the standard OG release.

"Venus" contains the beats of "Melvin Bliss - Synthetic Substitution" (1973).

Honestly I don't know much about this album or Slick Rick himself but then who cares as this record features "Run Away", one of the most impossibly cool songs of modern times.
It's quite simple : I don't understand a single line, which are barely rapped by a very loose Mr Rick anyway, but even so you get this fabulous feeling of unmatchable coolness reeking from every beat and rhyme of this mellow monument, like going through that moment of thrill and excitment of crossing the cool kids at school when you're a newbie and you feel you'll never ever be as slick, only it's twenty years later and you left school long ago... Let's not mention this totally hypnotic, smoky, casually dubbed-out and leftfield beats, hazy choirs and musical background...somewhere between a very blunted De La Soul and a dubbed-out deviant version of Bill Withers' "Lovely Day".
The fact that this was never released as a single (therefore no extended, instrumental, or even dub version, and no worldwide hit for Mr Rick) is a crime. Slick Rick indeed!!
