Keith, I suspect that you are not correct on this. I have a copy of Boston's Don't Look Back 35.8P-7 that came with an obi (black box obi, only titles listed on the back), and is gold-faced with machine-stamped matrix number. So unless someone placed an obi from a reissue on the CD that I purchased, I must assume that the early issue CBS/Sony discs did indeed have obis. The reason you never see them is that they simply have not survived the years. Also, since the gold faced discs were only issued in the early years (the latest one that I have is Earth Wind & Fire's Powerlight, which is 35DP-44), if you purchase a later issued disc such as the Pink Floyd Final Cut, with an obi that does not reference later issues, then it is as likely as not that you have an original issue and an original obi.
