Illustration of the Amphicar 7/70, dual prop amphibious car. The 7/70 refers to it's speed on water (7 naughts ) and 70 mph on the highway. The owner of this vehicle is friend John Bevins, a paraplegic who invented and installed the hand controls...he had previously patented the hand controls for his Harley too ! Proceeds from the posters toward victims of spinal injury.
