Close Encounters of the Third Kind, Production cast header board from CE3K

original production material

This is THE cast header board from the Close Encounters of the Third kind production strip board. The strips are missing.
A film production board or production strip board is used to organize a filmmaking project. It is a cardboard chart holding color-coded strips of paper, each containing information about a scene in the script. The strips, called production strips, can then be rearranged and laid out sequentially to represent the scene order that the Assistant Director will schedule the film. The sequential order of the production board will be in perfect sync with the shooting schedule.

The Cast Header works as a legend for the Production Board, and identifies the cast numbers with their characters.

So this is an unique item in the traditional process of movie making, nowadays there are software programs that do this thing.

This CE3K one has two sides, still dont know why. One of them with the title "watch the skies".
