The New York Anime Festival was held 7-9 December 2007 in the Javits Convention Center. If you missed it, but really need some of their limited edition logo merchandise, now’s your chance. They’ve put a store online with RightStuf.com (see this link to access it). They’re selling logoed shirts, calendars, “plushies,” and sake sets.
RightStuf, founded in 1987, “was one of the first players in the US anime industry,” and is a producer, distributor, and retailer for a whole slew of companies (there’s a list, with links, of those client companies on this page).
