Star Wars Shirts
I was able to get my hands on a D23 Guide Book a day early. While most of its contents are non-Star Wars related, I was able to find a great booth advertisement by welovefine.
While there appears to be no D23 exclusives, it is a great reminder of how many great shirts they have on-line.
