The following is an original animators draft for the Max Fleischer "Color Classic" cartoon A CAR-TUNE PORTRAIT (released June 26th, 1937). Note the original title was "Animal Orchestra". The draft does not include the opening sequence of the characters being drawn by an artists hand. The film must have run short and they added this sequence late in production.
Animators noted include Dave Tendlar, Eli Brucker, Nick Tafuri, Joe Oriolo, Bill Sturm, and Herman Cohen. The voice of the Lion conductor (orchestra leader) was provided by radio announcer David Ross.
