Yes. The stein will have a different piece of artwork. It will likely be the purple worm featured in the GC V Easley art.
Honestly, I did not realize there were souvenir beer steins for sale at GC IV. If anyone has an extra or wants to sell theirs, I would definitely be interested. Feel free to PM me.
No we sold out immediately. In fact we had an extra 24 from an order error and we still sold them out. Make sure to pre-order any items you really want.
FYI the steins from last year: I know that washing them in dishwashers has been removing the tint off the bottom of the stein, particularly the red tint. I haven't personally had this issue but I have seen it in some of the ones that came back to CT with one of our contingent. Then again, I don't have a magic dishwashing machine, I have to do it all by my own little mitts.
