Here are some scans from the April 1975 Cartoonnews (Combining Cartoon and Cartoon Club Newsletter) that featured some of Al Wiseman's work on the cover. The text inside reads:
"Al Wiseman has got to be one of the most prolific cartoonists in the business.
Besides drawing "Dennis the Menace" for Hank Kethum and the Hall Syndicate for more than 13 years, Al has sold cartoons to all magazine markets, major and minor, art directed motion pictures for Boeing Co., drew "Belvedere" for George Crenshaw, illustrated books for Prentice Hall, Inc., Alaska Magazine, Altair Industries, Celestial Arts, and Sullivan Behavoiral Books and coloring books for Physician's Art Service.
We've tried to select a variety of Al's drawings to show you the amazing versatility of this man."
