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:
“For Banquo’s issue have I filed my mind;
For them the gracious Duncan have I murdered;
Put rancors in the vessel of my peace
Only for them; and mine eternal jewel
Given to the common enemy of man,
To make them kings, the seeds of Banquo kings!”
—William Shakespeare (1564–1616)
“Many young girls are ... becoming trained nurses, whose gentle ministrations in the sick-room, skilled touch, patient watchfulness and unwearied vigils, are as great factors in the care of the sick, as are the professional physicians.”
—Lydia Hoyt Farmer (1842–1903)
