The paper work and the disc art
I can tell by the paper work and the disc. They're both seemingly the same, but when you've had the OG since back in the day and you've come up on the re-release in a used store, you can see that the 2nd disc's artwork image is a lot crispier looking and the insert/paper work has been scanned and re-printed on the re-release. It's just like X-Raided's album. The "X" in X Raided's name has be retouch/redesigned/updated in the re-release version and has a totally different look then the original pressing and the 1st Re-release. There are a total of 5 different version of his Psyco Active in my collection. I tend to keep all of the different variations of each CD; partly because I've ran out of things to collect and it helps me learn the differences. Heck even lyrics and music changes on some albums. That's why I knew which Mac Dre - Young Black Brother Blue Disc was the original. I study this stuff all of the time. When and if you get both version of this Fat Pat in your hands, you will see what I'm talking about. You can't recreate the cover artwork without disturbing something. The more you try make it more original-like, the more evidence is left for you to see the differ. Think about it. Crispy looking disc, but blurry/scanned looking inserts. Sometimes the inserts are so blurry on re-releases, because the manufacture either makes the image too dark or too light. Theres no way to do an exact match, unless the artist or his company kept the original picutures/images on a disc or CD-Rom disc. Even then it would still have to be pressed on the same printer with the same exact ink. The more you collect and the longer you collect, you'll know the difference at eye's glance, because your eyes and memory would have been trained to see the difference. I've been collecting since I was 10-ish. Hell I use to read everything on the inserts. Production, studios, features and all of that. Heck I still do. I don't claim to know everything, but I do know a lot. I've even learned a lot from other members on this site as well.
