Another Crystal Cube!
Another rarity to star in any collection. This one is based off of the 20th Anniversary art of modern Sonic with a TV that shows classic Sonic's face/portrait. But look! You can even see the picture on the TV screen within the cube! Certainly, it is an amazing work of art. The logo & inscription help give it a sense of depth. The inscription reads "Still Unstoppable After 20 Years"
It could be gotten from ebten. And naturally, it was a Japan exclusive

Price:
PS3 or 360 Pack: $125 (Including game, crystal cube, Sonic washcloth, and History of The 1st Stage CD White Edition) 3DS Pack: $108 (Same as above, but with History of The 1st Stage CD Blue Edition)
Of course, by the time anyone found out about it (it released Dec.1 2011) they were all sold out. This was likely because it was limited edition to only 500 ever made. What did the wash cloth look like? (what an odd pairing, a crystal cube and a random washcloth) Certainly, it's worth much more now than the initial price.
