Thank you for viewing! Showa Retro, Vintage, Onyanko Club Cassette Index, Rare!! This is a rare cassette index from Onyanko Club. I remember purchasing it through mail order back in 1986-1987. It is an unused item, but since it has been over a decade since the purchase, please understand and accept that it is a used item before purchasing. Cassette tapes themselves are becoming rare these days, but the official cassette index is probably a rare item within a rare item. If you were looking for one, how about this opportunity?
