Query: Review of THE BLOCKBUSTER TOY

GENE DEL VECCIO'S BOOK ON THE BLOCKBUSTER TOY IS EASY TO READ, HOLDS INTEREST, AND SUPPLIES A HISTORICAL PERSPECTIVE, AS WELL AS A CONCEPTUAL PERSPECTIVE, OF TOYS PROBABLY NOT FOUND ANYWHERE ELSE. IT SHOULD BE OF INTEREST TO ANY MANUFACTURER OR MARKETER OF PRODUCTS FOR KIDS (NOT JUST TOYS), AND OTHER MARKETING PRACTITIONERS, FOR THAT MATTER.
