I know its the same exhibit as moca, they are organizing it for the brooklyn museum, but I'm not sure about the limited edition stuff, I haven't heard anything about that matter. I'm going up to see it, possibly the weekend it opens but I have no money for anything right now
My new LV "must have" is a monogram shawl in champagne, I might just ask for that as my birthday present though. I love Murakami's stuff, being an art student I've done a few projects about him and this trip will fill in for a research paper topic as well, so I think it would still be a worthwhile trip, tickets are only $10, $8 if you have a valid student ID. The shop may still have some neat stuff, there were some cute pins and stationary on eBay from the LA show.
