The only image I could find of this extremely rare release, shows the single cover with the copied front slick glued to it; the same was done for the back. Plain blue labels for disc one and plain red ones for disc two.
Just as rare as 719/20 and same cover style with slicks glued to a single cover. Reportedly, also exists separately.
Offered for auction in Japan in December of 2014 by an Osaka based seller and seems to have attracted an ending bid of $2,500+.
