Slinky
Very early in the production history of Slinky, Helen Malsed of Washington developed ideas for Slinky pull toys. The company liked her ideas and added Slinky Dog and Slinky Train to their line in 1952. The Slinky Dog was a small plastic dog whose front and rear ends were joined by a Slinky. Malsed received annual sums of $60,000 to $70,000 per year for 17 years for her idea.
