The famous MGM film that followed in 1939 borrowed several elements from Eshbaugh's version: the switch from black and white to Technicolor and the carriage procession through the Emerald City have precedents in Eshbaugh's cartoon.
This 1933 animated film is one of the rarest items in the entire canon of Oz-related works.
Also in the 1930s, animator Kenneth L. McLellan tried to create a version of the second Oz book. He gained the support of Baum's widow Maud Gage Baum, but never found financing for his The Land of Oz.
