This is the ORIGINAL FIRST PRINTING of this poster designed by the fabulous Al Hirschfeld. Printed in the mid 1970s, it was created to advertise the launch of the Marx Brothers book Why A Duck, illustrated by Hirschfeld. The poster features a film still from the movie Duck Soup, with the lines from the scene captioned below in decorative bubbles. Note: This is NOT a reproduction.
