So I got the shirt pictured in the link above at a thrift shop for $1, as I figured it may be worth something more than that. I've scoured the internets and the only thing I could find that set a price on it at all was this post from 2002, where they say the auction started at $15 and "expect it to go a lot higher" (sauce: http://forums.bungie.org/story/storyarchive.pl?read=9917). Anybody know the relative rarity of this shirt compared to the other ones, and how much I should expect to get for it over ebay? Also does anyone know where the shirt came from? Preorder, promotional, or retail?
