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:
“Virtuous people are simply those who have ... not been tempted sufficiently, because they live in a vegetative state, or because their purposes are so concentrated in one direction that they have not had the leisure to glance around them.”
—Isadora Duncan (1878–1927)
“In European thought in general, as contrasted with American, vigor, life and originality have a kind of easy, professional utterance. American—on the other hand, is expressed in an eager amateurish way. A European gives a sense of scope, of survey, of consideration. An American is strained, sensational. One is artistic gold; the other is bullion.”
—Wallace Stevens (1879–1955)
