Exploration has a thing called "Lotus Legend" dated as released on 91/3/29 but no code. I think this is that thing. It has a mini LP cover but the 2 CDs (not 3) come in a jewel case.
There is a C2K46764 released on 91/2/26 - this is not that.
There is also a 5099746794323 which is just normal jewel case.
