From The Web:-

 I   INSANELY RARE   "DOUBLE"-STRICKEN (MISPRINTED) COVER WITH TWO DIFFERENT STEREO BANNERS FOUND ON TOP OF THE FRONT COVER. NAMELY, WHEN CAPITOL REALIZED THAT THE BROWN STEREO LOGO ON THE DARK GREEN BACKGROUND OF THE FRONT SLICK WAS DIFFICULT TO READ, THEY PREPARED REVISED BACK LINERS THAT HAVE THE STEREO LOGO BANNER ON THE PORTION THAT WRAPS AROUND TO THE TOP OF THE FRONT COVER. THEREFORE, THE FRONT COVER SLICKS THAT HAD THE STEREO LOGO BANNER PRINTED ON THEM, WERE TRIMMED AT THE SAME PLACE AS MONO SLICKS TO REMOVE THE STEREO DESIGNATION. HOWEVER, ON THIS PARTICULAR COPY, THE FRONT SLICK WAS NEITHER CROPPED NOR COVERED BY THE BACK SLICK, CAUSING TWO DIFFERENT 'STEREO' BANNERS TO APPEAR ON THE FRONT PANEL: ONE (BROWN) PRINTED ON THE GREEN BACKGROUND, AND THE OTHER (BLACK) PRINTED JUST ABOVE IT, ON THE WHITE TOP MARGIN OF THE COVER
