The visual development artists that worked at Disney Studios over the years pioneered all kinds of different styles for characters as well as for environments. Sometimes their artistic vision made it intact into the final film, other times their work provided only a subtle influence.
One thing is for certain, the range of expression was huge. What you see here are images that are realistic and tonal, others are graphic and flat. They all try to set a mood or illustrate a particular situation. Story people were involved in suggesting designs as well.
I thought it would be fun to show one….just one visual from each of the classic Disney films. Post one (of two) covers the features from Snow White, 1937, to Mr Toad from 1949.
