I happened to find this disc from my bookshelf, which seems to be a reprint of this release and a unique catalog number (TTEC-0007) was apparently issued. I can't for the life of me remember when, where and how I got this one, but I purchased some of Troubadour/Synergy releases in the past, mostly via Ayako Saso (she directly replied to my mail O.o).
Edit: wow, the image was too big!
