Ben Rubin has worked in television for 25 years and owns The Mint Farm, a marketing company that creates commercials and promotions for television networks and social media.
However, he has recently become a star on social media himself by posting images of furry monsters superimposed on subway travelers to Facebook and Instagram.
His "Subway Doodle" creatures run the gamut from cuddly to blood-curdling - kind of like New York City subway riders themselves.
