Chatter Telephone
The Chatter Telephone is a pull toy for toddlers 12 to 36 months of age. Introduced in 1961 by the Fisher-Price company as the "Talk Back Phone" for infants and children, which was updated to the name Chatter Telephone in 1962, is a roll along pull toy. It has a smiling face, and when the toy is pulled, it makes a chattering sound and the eyes move up and down. The toy has a rotary dial that rings a bell, and was conceived as a way to teach children how to dial a phone. The original version  was made of wood, with a polyethylene receiver and cord. In 2000, Fisher-Price changed the rotary dial for a push-button version with lights in an effort to modernize the toy, but consumers complained and the rotary version returned to the market the following year. The Chatter Telephone was designed by Ernest Thornell, whose daughter Tina would drag around a metal phone while playing. This gave him the idea of adding wheels, which with a bent axle permitted the movement of eyes, adding to the "whimsical" nature, that Herman Fisher desired of all Fisher-Price toys (from phone conversation  with Ernie Thornell and recollections of Herm Fisher by John Smith). From its introduction through the 1970s, the Chatter Telephone was Fisher-Price's best selling product. It has been cited as one of the company's offerings that helped save Fisher Price in the 1990s following a failed attempt to market toys for older children in the late 1980s, and enjoys continuing popularity. It is available both as an authentic reproduction and in a modern form.
