Photo Essay: Ford Mustang Prototype
The Ford Mustang made its world debut at the 1964 World's Fair in New York, and since then it has gone through numerous incarnations as Ford's longest-produced car. Each generation underwent pre-production development, and the prototypes built by Ford show the evolution of the Mustang.
