Mike Roy, 75, an illustrator and artist who produced comic strips, comic books, and cartoon drawings for West Virginia racetracks, died of complications related to cancer March 25 at his home in Springfield.

During the late 1940s, Mr. Roy did the drawings for the comic strip "The Saint," which was published in The Washington Post, the New York Herald Tribune and other newspapers. He also did drawings for the Nero Wolfe comic strips in the New York Post and other newspapers and collaborated with mystery writer Mickey Spillane on comic books.

In 1950, he moved to Washington as a visual information specialist with the U.S. Information Agency, and he later was a partner in a film production company known as Hi-Roy Film Productions, which specialized in horse racing.

In the 1970s, he did public relations work and produced a cartoon booklet and racing primer called "They're Off," for Charles Town and Shenandoah Downs in West Virginia.

His publications also included space booklets for the National Aeronautics and Space Administration and freelance illustrating for private corporations and organizations. He had continued working until losing his eyesight about three months ago.

Mr. Roy was born in the Hudson's Bay area of the Canadian province of Quebec and grew up in Lewiston, Maine, and New York. He served in the Army during World War II, and he parachuted into France in the D-Day invasion of Normandy on June 6, 1944. He was wounded twice during combat operations in Normandy.

A native French speaker, Mr. Roy later served as an Army interpreter in France and then in Belgium.

After the war, he studied at the Pratt Institute in New York and did freelance artwork. He began a comic strip collaboration with Leslie Charteris, the author who in 1928 created the Saint, a fictional mystery character named Simon Templar who was tough yet debonair, with a weakness for pretty women. The Saint harassed police and the underworld alike, and he enjoyed his work immensely.

In addition to subsequent Nero Wolfe comic strips, Mr. Roy also produced comic books featuring stories about entertainer Jackie Gleason and baseball star Mickey Mantle. He did comic books for Dell Comics, D.C. Comics and Famous Funnies. His government work in Washington included promotional assignments for Edward R. Murrow at USIA and Smokey Bear Cartoons.

A horse racing enthusiast all his life, Mr. Roy was a former art director for Horsemen's Journal. He also had served as the art director for Funk & Wagnalls Encyclopedia.

To produce "They're Off," the cartoon booklet racing primer, Mr. Roy spent weeks on the backstretch of Shenandoah Downs and Charles Town, compiling information and drawing sketches to record a day in the life of a thoroughbred racehorse, beginning with the early morning workout.

The booklet also included illustrations of the horses being shod, fed, attached to an automated hot walker and then, as seen from the announcer's booth, through a race. There were drawings of various pieces of equipment, including bits and bandages, and a section on types of wagering and classifications of races being run.

Mr. Roy was a member of the National Cartoonists Society and the Capital Yacht Club.

His avocations included American Indian art and lore, and he was fluent in the Cree Indian language.

Survivors include his wife of 49 years, Adrienne Mootafian Roy of Springfield; a daughter, Annette Roy Murray of Merritt Island, Fla.; three grandchildren; and a great-grandson. HUGH B. SOUTHERLAND Richmond Doctor
