The Duncan Professional yo-yo was originally introduced in 1971 by Duncan. In 1974 it changed shape from the tournament shape to the Slimline shape. Since then it has been used as their primary advertising yo-yo up until recently. When Duncan Acquired Playmaxx it started using their ProYo for the bulk of its yo-yo advertising, all but discontinuing the Professional Slimline. There have been many versions of the Professional including the Superhero line, most of their advertising and even for the 1979 Duncan Yo-yo Olympics.
Famous quotes containing the words duncan and/or professional:
“So long as little children are allowed to suffer, there is no true love in this world.”
—Isadora Duncan (1878–1927)
“The relationship between mother and professional has not been a partnership in which both work together on behalf of the child, in which the expert helps the mother achieve her own goals for her child. Instead, professionals often behave as if they alone are advocates for the child; as if they are the guardians of the child’s needs; as if the mother left to her own devices will surely damage the child and only the professional can rescue him.”
—Elaine Heffner (20th century)
