It's doubtful Mr. Potato Head helped inventor George Learner achieve his goal of getting kids to eat more vegetables, but he certainly had their attention with this iconic toy.
The original Mr. Potato Head was just a set of plug-in facial features that could be poked into real potatoes. The plastic spud body came later. Some of Mr. Potato Head's popularity may be owed to the fact that it was the first toy to have its own dedicated TV commercial that marketed directly to children. After the TV ad aired, Mr. Potato Head became a huge hit.
