Off Our Rockers: Cartoons and Homespun Humor to Perk Up Your Life with Laughter! (Paperback) (ISBN-13: 9781492148982)

Duncan's cartoons have appeared in local, national and overseas publications. His work has taken him to 28 countries.

In 1974 he received the Whitney M. Young Human Relations Award for his interracial cartoon strip, Winner Williams.

Hall's doctorate is in cross-cultural communication from the University of the Witwatersrand, South Africa, where he researched the pictorial perception of South African children, including Zulu and Tsonga tribes, in order to become a more effective illustrator. His research has been published by the University of Cambridge, England, New Readers Press, Syracuse, New York, and The Human Sciences Research Council of South Africa.

Upon his return from Africa, he taught cartooning and advertising for seventeen years at Central State University in Oklahoma, now the University of Central Oklahoma.

As director of International Services for the International Center for Humor and Health in Edmond, Oklahoma, he presented workshops on humor and health in South Africa, South America, Europe, Asia and the United States. He specializes in humor and health training for senior citizens.

Hall has four sons, many grandchildren and great-grandchildren, all of whom keep him well-supplied with laughter and cartoon material.

Hall's wife, Lois Smith-Duncan, died in 2011. She played the role of Nurse Ease-A-Pain in Dr. Duncan's hospital and retirement home programs.

Aside from his "Off Our Rockers" workshops and writing children's books, his hobbies are ballroom dancing and exploring world history.
