This is called "Sonic 20th Anniversary Towel" but, is it big or small? Also, what kind of a towel is it, the fabric looks pretty thin here. It's nice looking, in all blue, dark blue and white. The left side has modern Sonic, while the right has classic. There are also lots of cute little 'micro Sonics' scattered over the logo and around the larger graphics. Where did this come from? Is it a prize?
