First press had orange sleeves and orange lyricsheets. A few of the following presses have orange sleeves as well, but it's a mess what presses there are. There are different versions though. Differences in sleeves (orange or yellow, glossy or not), lyricsheets (orange, yellow, white and xeroxed) and matrixes all accur. Later presses have a yellow sleeve and ofcourse a different matrix. There's even a version which plays on 33 RPM on the one side, and on the other it's 45 RPM, if that's a miss press or a common press: no one knows.
Rev.txt says this about the first presses: Orange sleeve. A few of the following presses have orange sleeves as well. The matrix matches the 3rd pressing of the Schism press and stayed that way for a number of repressings. And about later presses: black vinyl, yellow paper sleeve, matrix etchings change so another test pressing should exist. It is not known whether the new matrix coincides with the change of sleeve color.
