I stumbled upon this curious artifact while going through some stuff in my office at Mirage yesterday. It's an official-looking proclamation for "Teenage Mutant Ninja Turtles Day" in Los Angeles, California, in 1993 -- March 19, to be precise. It's even signed by then-mayor Tom Bradley.
I don't really remember much about this, but from reading the proclamation I gather that it was something done in connection with a special world premiere screening on March 6, 1993 of the third live-action Turtles movie, the proceeds from which were to benefit several different charities. -- PL
