These are the Nine Old Men Flip Books. Back in Disney’s hayday there was a change in the organisation which meant that instead of multiple animators working on each scene, there was one person dedicated to the scene. This led to better work because the single animator had a fuller understanding of the character interactions. There were nine lead animators fondly known by Walt Disney as the ‘nine old men’ and this collection of nine flip books commemorates each of them respectively. It includes scans of the original pencil drawn animation before colouring or compositing. There are even notes written on the side of some pages. IT’S AMAZING.
