Norm Ferguson joined Disney’s animation team in 1929, and quickly had a major influence on the studio’s style. In The Chain Gang, the bloodhounds he designed to chase Mickey Mouse impressed Disney with their expressiveness. Ferguson went on to animate Minnie’s dog Rover with a variant of that design in The Picnic. The two cartoons, joining the public domain in 12 days, show a clear development into the dog who Ferguson would also animate in later cartoons named Pluto. #PublicDomainDayCountdown
