In 1940, LIFE Magazine featured Moran in their article "Speaking of Pictures" and the American audience was in awe.
Breaking in via advertising work for Sears-Roebuck, Moran went on to magazine illustration, movie posters ("Something for the Boys" 1944) and even co-published with Robert Harrison an early "girlie" magazine, Beauty Parade, contributing covers, sometimes under his middle name non de plume, "Steffa", and he later contributed pinups to other Harrison magazines such as Flirt, Wink and Giggles.
In 1946, Moran moved to Hollywood though he had already painted many movie stars including Betty Grable, for publicity posters. Soon after his arrival, he interviewed a young starlet named Norma Jean Dougherty who wanted to model for him.
After a move to Las Vegas (circa 1955) and several years of living in the fast lane, Moran decided to devote his time to painting fine-art subjects in oils, with nudes as his favorite theme. Signing with Aaron Brothers Galleries, he painted for collectors until 1982, when his eyesight failed.
