[3] Beall received tutoring from the Canadian–American painter George Brant Bridgman at the Art Students League in New York City.

Some Meredith magazines that he produced paintings and colored drawings for included Collier's, Vanity Fair, Cosmopolitan, Woman's Home Companion, Saturday Evening Post, American Family Circle, and This Week.

[5] Beall's 1936 painting of President Roosevelt for Collier's cover page led to the position as art director for the Democratic National Committee.

[10][11] Beall's 1945 Treasury poster painting of Joe Rosenthal's photograph of the raising of the replacement American flag on Iwo Jima was used for the war campaign in the Seventh Loan drive.

[16] The loan promotion brought in more than $26 billion in six weeks' time to help end World War II.

The poster from this art work was labeled "In The Strength Of Great Hope We Must Shoulder Our Common Load."
