Vintage Firestone Stereon "Can Save You Money" advertising pen

Description

Cool piece of vintage Firestone advertising. Item consists of a ballpoint pen encased in a clear plastic shaft surrounded by shredded US paper currency. Advertising is for Stereon, a polymer additive to adhesives. Pen is in good condition and ballpoint pushbutton mechanism works, but ink long ago dried out unfortunately. Still makes a unique collectible. I've never seen a pen with shredded paper money inside. I don't know what time period this item dates to. Sold As-Is/ No Returns
