French inspired ironwork incorporating hidden names and initials are prominent features on the gates and balconies of Historic New Orleans. Disneyland's New Orleans Square follows suit with similar decorative details. Walt and Roy Disney's initials have been hidden in the decorative iron railing found on the Disney Draem Suite's balcony (initially conceived as an apartment for the Disney Family, currently the Disney Dream Suite).
Update: The initials were highlighted in gold during the creation of the Disney Dream Suite in 2008.
