Left Fist (Bloated)
Perhaps the most iconic Transformer of all time, the original Generation 1 Optimus Prime was on the Xmas want list of every boy in North America in 1984. Of note to collectors should be the various variations on smokestack length, missle colour, Roller colour, fist and rifle size and the presence of stickers vs. raised panels on the floor of the trailer. The toy has also been re-released numerous times with slight changes along the way. A must have for any serious TF fan.
