Maddock was an artist who worked for several decades in the advertising industry. He graduated from the Chicago Academy of Fine Arts, worked on campaigns for GM, Dow, Goodrich, Sohio, and other, while employed by several ad agencies. After retirement he lived in Hawaii where he edited a local newspaper and devoted more time to his watercolors, which were exhibited in local galleries.
The collection documents the life and career of Clark Maddock, from his early years as a bandleader, through his work in the advertising industry and subsequent retirement. There are clippings and a few photographs relating to his musical career, but most of the collection relates to his work in the advertising industry for several ad agencies, and includes original artwork for print advertisements (especially GM's "Mr. Goodwrench" campaign) letters, flyers, a sketchbook, drawings, storyboards, photographs, and awards.
