Its a fake. The labels on the CD's themselves look like something you can make on your computer. There's none of the usual writing on the CD's either; around the outside or inside edge. The albun sleeves look like computer printouts, as well.
The only thing that looks real is the UPC code. And it is. Its just not a Pink Floyd UPC code. Its from an Eric Clapton 2 CD album. My guess is that they used the Eric Clapton CD as a template and just left the UPC portion alone so it looks real. They probably figured that no one would go through the trouble of looking it up.
That said, if it sounds good who cares. Someone probably did go through the trouble of making a good copy. I know a lot of people who would rather listen to a CD that was copied from vinyl instead of a regular copy.
