Ka-Yo Musical Yo-Yo

Description (Brief)
This steel yo-yo was made by the Cayo Manufacturing Company of Benton Harbor Michigan in the early 1930s. There is a "Captain's Wheel" lithograph pattern design printed on one side in gray, white and black. Julius N. Cayo founded the Cayo Manufacturing Company as a metal stamping business and began making yo-yos in the early 1930s. It was called a Musical Ka-Yo, so not to infringe upon the Duncan Toy Company's trademark of the term "yo-yo." It whistled when spun due to holes in its sides.

"Julius Cayo was my great uncle. He was an amazing inventor of many household items and toys. He worked with Duncan actually helping with design variations. He also went to England and was the manager overseeing the construction of Duncan's yo-yo manufacturing plant. Julius invented and manufactured the rubber strip on the dustpan, the machinery to make paper lampshades to replace the more expensive fabric ones. My mother use to say that everyone could afford something for a nickel or a dime, so he tried to make toys, and everyday items for the everyday people. As a girl I loved hearing the stories about how he invented an item and then tools and machines to mass produce them. Julius and his family were French Indian mixed blood. Or known as Metis originally from Canada."
