Velvet Underground, The ‎– White Light/White Heat

Hi, I seem to have an unusual copy of this album which someone may have some knowledge of. The front cover is black without the skull and it has cat number V6-5046 top left and STEREO top right. It is made from very thick cardboard and the back cover is almost sepia rather than black and white with the mis-spelling of Here she comes now, Lou credited for lead guitar but no crediting of Andy Warhol for cover concept. (I read on another site that the first pressings didn't have Andy Warhol credited, but his name was added to subsequent editions). Also the spine says "V6-5046 White light/White Heat The Velvet Underground Verve" as indicated is on the original edition.

However, it is on the record itself where there seems to be the real unusual attributes. It is the black rather than blue verve label and the matrix codes are unusual as Each side has both the mono and the stereo matrix codes. Etched into the run off groove on side A is the matrix code V6 5046 MGS 1258, and it is indeed a stereo recording on Side 1. Etched onto the run off groove on side B, however, is the matrix code V 5046 Side 2 MG 1258, and is indeed the mono recording of side 2! Has anyone come across a similar version of this album?

Cheers,

Ian
