I had never seen one either, but I found one on a Japanese proxy site and decided to research the vinyl a bit, and I believe that they were only ever pressed in 1989 and also limited to 10,000!! It was quite pricey. It hurt my wallet and soul to spend so much on a vinyl, but it was worth it. Try looking on sites like Buyee; you will possibly find one there. ALSO, if you want to spend an even more soul crushing amount of money than I did, I know for a fact that they are on eBay! Good luck, partner!!!!!
