as the years go by, and technology progresses, people get better and better at creating knockoffs that look really authentic. Anyone remember the Together when... bootleg? It's from 2007 too. Amazing that it's completely unofficial too. You'd never know it wasn't real if you weren't a genuine ayu fan and knew it was only a digital single. To top it all off, it's made buy a Chinese bootleg guy. I have a feeling that within the next 20 years you won't be able to tell what's authentic or fake anymore.

It's so authentic and good looking that even though I know it's fake, I kind of want to ask the guy if I can buy a copy off of him.
