Baldwin Piano Company, an American piano brand, was founded by Cincinnati piano teacher Dwight Hamilton Baldwin in 1862. The pianos were highly popular through the 19th and early 20th centuries. Baldwin factories were used during World War II to manufacture military aircraft components. After the war, Baldwin integrated manufacturing techniques learned during that period into the design of its newer piano models.

Trix is a fruit-flavored cereal made by General Mills and marketed to children. The Trix Rabbit is the mascot for the cereal brand, and for years, he was featured in commercials trying to get a taste of the cereal but was always stopped by children repeating the tagline “Silly Rabbit, Trix are for kids.”

In 1976 and 1980, a marketing campaign allowed children to decide if the Trix Rabbit was allowed to eat the cereal. Consumers were able to cast a vote by sending in a cereal box top. Those who voted were sent either a “Yes” or “No” button based upon their vote. The result of both elections was “Yes”, and the rabbit was featured in subsequent commercials eating Trix.
