Which of these was the first toy advertised on television?

Mr. Potato Head is an American toy consisting of a plastic model of a potato "head" to which a variety of plastic parts can attach — typically ears, eyes, shoes, hat, nose, pants and mouth.

Mr. Potato Head was invented and developed by George Lerner in 1949, was first manufactured and distributed by Hasbro in 1952, was the first toy advertised on television and has remained in production since.

In its original form, Mr. Potato Head was offered as separate plastic parts with pushpins to be attached into a real potato or other vegetable. Due to complaints regarding rotting vegetables and new government safety regulations, Hasbro began including a plastic potato body with the toy set in 1964.
