The Ralph Heimdahl Papers contain eight record series: Bugs Bunny Newspaper Comic Strips, NEA Booklets and Pages and Published Sunday Comic Strips, Bugs Bunny and Looney Tunes Picture and Comic Book Materials, Other Published and Unpublished Comic Strips, Rough Character Sketches, Anatomical Drawings and Watercolor Paintings, All Other Drawings, and Personal and Other Materials.

Series 1: Bugs Bunny Newspaper Comic Strips

Bugs Bunny began appearing in a newspaper comic strip in the early 1940s. The Sunday strip first appeared in newspapers on January 10, 1943 and drawn by another artist. Heimdahl began drawing the Sunday strip on October 5, 1947. The daily strip, introduced and drawn by Heimdahl, was first published in newspapers on November 1, 1948. Heimdahl would illustrate both strips until the fall of 1978.  The daily and Sunday Bugs Bunny comic strips ended in late December 1990.

In the Bugs Bunny daily and Sunday strips, Bugs is often shown trying to make a buck by selling items or providing services to his friends Porky Pig, Petunia, and Elmer Fudd. Some of Bugs’ businesses are: “Bugsy’s Toupees,” “Bugsy’s News Stand,” “Bugsy’s Beanery,” “Bugsy’s Used but not Abused Furniture,” “Bugsy’s Confidential Loan,” and “Bugsy’s Watch Repair.” Sylvester is typically a foil to Bugs, trying to mooch money or a free meal as often as he can. Other frequent gags include Bugs competing with Petunia for time on the pay phone, babysitting Porky’s nephew Cicero, or working for Mr. Schnoogle and Schnoogle's various businesses.

An item by item inventory of the newspaper comic strips is available.
