Runci was a portrait artist in Hollywood when he was approached by a calendar company for pin-ups. Martignette notes that Runci girls frequently get caught in compromising situations climbing a fence to flee a bull, dress blowing up on a Ferris Wheel ride.

Runci's early 1950s girls are rosy-cheeked, voluptuous, often blonde Marilyn Monroe-types whose wholesome sensuality radiates off the canvas. He also dabbled in the glamour-gown sub-genre, creating startlingly life-like effects in the silky folds of garments. Martignette speculates that Runci's artist wife may have likewise done similar, but slightly looser pin-ups also under the singular "Runci" by-line.
