I've got both the regular edition and the first pressing of this CD. I had Mikado Laser Japan (in San Francisco's Japan Town Mall) special order the CD for me in 1994 (iirc), several months after its release -- which meant that I missed out on the first pressing. Purchased brand new, the regular edition consisted of the CD, booklet, customer reply hagaki card, and obi (black, with red & white text).
I only managed to acquire the first pressing a few years ago, when I happened to stumble across a $7.00 used copy at the Book Off in Torrance, Calif. -- prior to this, I hadn't even been aware of the first pressing's existence. The first pressing was identical to the regular edition, with the following exceptions:
> no obi
> "book-case"-style illustrated cardboard slipcover
> 6-page full-color sticker book
> protective clear vinyl slipcase with resealable adhesive flap (with a large red ovaloid sticker on the front, proclaiming the 2 bonuses for buying the first pressing: the book-case slipcover and the sticker book)
Since the used copy I bought still had the original clear vinyl slipcase and customer reply hagaki card, I had always assumed that the first pressing never had an obi of any kind -- with the exception of some unfortunate sunfading on the spine of the book-case slipcover, the original owner appeared to have taken great pains to keep all the original parts of this first pressing together.
