Interpretations
Scholars who interpret The Wizard of Oz as a political allegory see the Emerald City as a metaphor for Washington, D.C. and unsecured "greenback" paper money. In this reading of the book, the city's illusory splendor and value is compared with the value of paper money, which also has value only because of a shared illusion or convention. It is highly likely that the Hotel del Coronado influenced its description in later books, as well as in the artwork by John R. Neill.
