Two different top obi exist for this. The most common by far is the white, "LD 15th Anniversary" obi. The other one is black, very rare, a much better match for the jacket art. The only difference on the sleeve, is the price: regular obi jacket shows both prices of ¥7700 and ¥7931 tax included, while black obi jacket shows only ¥7700. Possibly the black obi version could be a reprint, from a time when the tax had been raised to 5%.

Terrible transfer! Looks like it's been transferred from an overly bright print. Colors do not look anything like the other transfers. Go for the THX squeezed version or stick to the US THX discs!
