DIY: BACK TO THE FUTURE - SAVE THE CLOCK TOWER flyer
“Save the clock tower!” said the concerned women in Back to the Future. As she handed Marty McFly (played by Michael J. Fox) a flyer, the prop for collectors was born. And according to a Screen Used auction, the flyer’s dimensions were 8.5 x 11.
There's an awesome print-out version from The Replica Prop Forum (TheRPF.com), a great community for creating and building replicas from your favorite films!
