 Charles Darrow drew the designs with a drafting pen on round pieces of oilcloth, and then his son and his wife helped fill in the spaces with colors and make the title deed cards and the Chance cards and Community Chest cards.After the demand for the game increased, Darrow contacted a printing company, Patterson and White, which printed the designs of the property spaces on square carton boards.Darrow's game board designs included elements later made famous in the version eventually produced by Parker Brothers, including black locomotives on the railroad spaces, the car on "Free Parking", the red arrow for "Go", the faucet on "Water Works", the light bulb on "Electric Company", and the question marks on the "Chance" spaces, though many of the actual icons were created by a hired graphic artist.
