The original wooden version of the Butterfly was first produced and sold in 1958 by Duncan Toys, and was one of its most popular yo-yos before the bankruptcy in the 1960s. It was the very first Butterfly-shaped yo-yo, as well, its design having been invented by then-demonstrator Wayne Lundberg. With its shape, the Butterfly made it easier for players to land string tricks effectively. This yo-yo had essentially planted the seed for future generations of dedicated string trick yo-yos, especially those that would come to be produced by Duncan.
