There is a new book out entitled The Treasures of The Hard Rock Cafe. It's basically a photographic book of memoribillia that they've accumulated over the years. There are several pages dedicated to Prince stuff including photos of the cloud guitars (white, blue, yellow), couple of outfits (Purple Rain & Lovesexy era). There's also a really nice 2-page spread of the PR trenchcoat outfit enclosed in a glass case along with the guitar with the see-through body that has flowers embedded into it. A beatifully photographed book for anybody with an interest in rock memoribillia.
