In the summer of 2009 I got in contact with Alan Mintz, the band's attorney. He was the guy that shopped Nirvana their record deal and represented them for several years.
So I asked him about how many copies there were made and how many "variations" there is of this tape since my tape is a bit different from the copy found on www.sliver.it

My copy has this printed on the front:


The copy found on www.sliver.it has this:


But anyway, this was his reply to my questions:

"Based on your picture, that tape was made by Bret Hartman who was an A&R guy at MCA Records at the time. He was the first major label exec to make them an offer. The tapes I sent out to get them their record deal did not have his or John Silva's name on them. That is the full repertoire of the demos we had at the time. I suspect that he probably made 20-30 of those. I made about 15 myself I would think, but as I said mine would have only had my name as contact, and were made in my office, not at the duplication company listed on your tape. Many of the original tapes I sent out when shopping their deal would have had only 3 or 4 songs.
