Thelma Packman Gray, 91, of West Chester, a pioneering advertising and public-relations executive, died of heart failure Dec. 29 at home.
Mrs. Gray became a partner with Gray & Rogers in 1945, and established the Philadelphia ad agency's public-relations division. Jerome B. Gray and Edmund H. Rogers had founded the firm in 1931, and the late 1940s its clients included Bell Telephone of Pennsylvania, Chilton Publishing Co., local hotels, and food and drug companies.
In 1948, when a new client, the Allied Florists Association wanted to gain national exposure on a limited budget, Mrs. Gray had a brainstorm. That year, both the Republican and Democratic National Conventions were in Philadelphia, so she arranged to have a committeewoman present a floral arrangement in the shape of a flag to Thomas Dewey the night the Republicans nominated him as their presidential candidate.
