This is the original release pressbook for Cinderella (1950). It is noted as Campaign Book A because it was accompanied by Campaign Book B, which contained a record-making amount of merchandizing. I will post Book B, shortly. This one, with 20 pages of promotional goodness, is pretty amazing all by itself. Disney was incredible at tie-ins merchandising for all of their animated movies. After Pinocchio (too dark), Bambi (too real), and Fantasia (too cerebral) didn't do well at the box office, putting Disney in the red, Cinderella (just right with its struggling local girl makes good story) saved the day.
