Prod. 2229 - Mr. Duck Steps Out
Directed by Jack King, Asst. Dir. B. Newman, Layout Bill Herwig,
Secretary Marie Desnoit - this is draft no. 4 dated 10/10/1939.
As noted several other places, these drafts were never historical documents, but road maps to the person responsible for the bulk of the drawings (Animator/Effects Animator). Often, mainly on features, the actual Supervising Animator is not credited.
(Note the notation for the footage: first the actual Screen Footage, then (with an * in front) the animation footage as e.g. "Scr" (= same as Screen Footage), "Scr & 1/2" (= 1.5 times Screen Footage) or "3/4'S" (= .75 times Screen Footage)).
