That said; I've never made any secret of the fact that I doubt nearly every word he speaks and generally think of him as a dishonest person - at least with regard to his Original Vision Bullshit Story. However, I don't think he would blatantly copy something that closely and then claim it as his own. Conveniently leave it out of any discussions and hope no one ever noticed? - you bet. Steal and change the paint job? - no.

My take is post-Star Wars on those pictures. The clothing is correct for my high school years. (shut up) ;-)
