Two different covers exist for this pressing on "Arsenal". The vinyl and labels are the same.
Both versions have the same black/white printed sheet wrapped around and glued to the cover. The difference is that one is an over-sized paper envelope and the other is a white card stock standard record jacket.
The record was definitely mastered in 1981, and the test pressing may have been made in 1981, but the standard release didn't come out until early 1982.
500 copies were pressed, including both variants of the cover.
