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.

“We may not all break the Ten Commandments, but we are certainly all capable of it. Within us lurks the breaker of all laws, ready to spring out at the first real opportunity.”
—Isadora Duncan (1878–1927)
“The belief that there are final and immutable answers, and that the professional expert has them, is one that mothers and professionals tend to reinforce in each other. They both have a need to believe it. They both seem to agree, too, that if the professional’s prescription doesn’t work it is probably because of the mother’s inadequacy.”
—Elaine Heffner (20th century)
