Abundantly visual and painstakingly detailed, this is the definitive reference to vintage Transformers, some of the most desirable toys found on the secondary market. In 1984, Hasbro quietly infiltrated the toy aisles with a series of robots based on Japanese robot toys. These "transformable" robots were divided into two camps: Autobots and Decepticons. With die-cast metal parts, rubber tires, working action features and sometimes-firing missiles, these robots quickly changed to jets, cars and other weapons. Fueled by four live-action Transformers movies, values for the toys are skyrocketing. On eBay there are more than 93,000 listings for Transformer auctions just in Action Figures alone.
