Granddad's "trick" car

Hot rod, jalopy, "trick" car...whatever you want to call it.  You look at this car and then consider him adding a Rams head hood ornament on his 1963 Ford Galaxie 500 XL and you figure he liked cars and liked customizing.  This car was made up of parts from different cars so hard to tell what's going on.  He used this car in parades.  You could drive the car from the back.  The driver could pull off the steering wheel and hold up on the air and someone could still steer...maybe using knees.  He built this himself. The photo is from 1958 which means he was about 56 at the time.
