Super rare Japanese Lamb first release in 1975 with OBI. Includes insert with Lamb story and lyrics in Japanese. Charisma catalog numbers RJ-5162 / RJ-5163. I can't explain why this 1975 release has an earlier catalog number than the Japanese Trespass released in 1974.
Re-released from Japan in 1977 (SFX-10022 / SFX-10023), 1983 (15-PP-31/2), 1986 (20VB-1099/1100), & 1988 (VJL-1011/2)
It is possible to use these catalog numbers to tell the approximate time of release, but they are actually price codes. RJ-5 was originally sold for 2,200 Yen, the SFX originally sold for 4, 000Yen, the 15- sold for 3,000 Yen (1,500 x 2), etc.
