Ha, I too had those Star Trek III die-cast ships. It was crazy to me that the BOP had Star Trek written all over it...
It was like a collector set of Superman themed Matchbox cars I had. There was a "supercar", a Lex Luthor car, and curiously was also a Daily Planet newspaper delivery truck with a headline on the side about Superman saving the day along with a depiction of Clark Kent opening up his shirt to reveal the mighty "S". Kinda figured ol' Clark might have had issue with being outed so publicly by his own paper.
