He's a BIG Big Jim.  I'm amused by his shoes.  They had that hinged door thing on the heel.  Putting them on was kind of like driving a car into the garage and closing the garage door. I always wondered who came up with that solution..  He also had those 3 psychadelic discs that attached to his brain when you opened his face like the hood of a car.  He must have been co-designed by Monogram.   

Wasn't he the first action figure to use velcro rather than zippers or snaps?.
