right, yeah I see what you are saying. It's a little weird.
Edey gave the tapes back to Lee, as I understand it, once Seeds folded. It makes sense that they are following the Earthforms artwork/etc. The presence of the plants on the cover denotes a Seeds release (they all have some variation of it). It's weird to me that Gunter never reissued it himself if he ostensibly has "rights." But go figure...
