Early Sketch of Fire Convoy from designer Hisashi Yuki

To mark the 15th Anniversary of Car Robots, what we called Robots in Disguise in the west, Takara designer Hisashi Yuki tweeted out an initial draft sketch of what would become Fire Convoy (Optimus Prime). As you can see below, it shows off some very cool design cues that were not carried over to the toy, like the Maximal insignia on his chest (this was the first time the Transformers brand was going back to Autobots and Decepticons since Beast Wars). Yuki was the designer for Fire Convoy / Optimus Prime and the gallery of the toy can be found here,
