CLAMP has designed a Yuuko Blythe for the 10 Happy Memories exhibit celebrating Blythe's 10th Anniversary. There are plans to release a doll, [B2・ HOLiC], this fall. I think this is in reference to the Yuuko doll. They previously collaborated to exhibit a Watanuki and Cardcaptor Sakura doll last year.
Date: July 25th, 10:00-21:00
Venue: Parco Factory, Tokyo
