CPCA-10166~70: Okami Original Soundtrack

[hcs]

I just got my hands on a copy today, and I'm curious about some of the markings on the materials. In addition to the catalog number CPCA-10166~70 is TGCS-3340~4. Also, on the back of the box, next to a symbol I don't recognize, is the date 2008.05.30, though the release date 06-05-31 is in a box. The TGCS numbers are what's actually pressed on the CD (though the label has both CPCA and TGCS). Is this a reprint? If not, what does the 2008 date mean? It can be vaguely seen, though out of focus, in Secret Squirrel's scan.
