== Template:Infobox World's Fair == 

 Hi there; I've got an issue with Template:Infobox World's Fair and was not sure to discuss it; as its creator you would seem most knowledgeable. The template is used for many expositions which were retroactively recognized by the BIE, such as the Centennial Exposition. All these expositions have the infobox header "EXPO [city] [year name]", which is quite strange for expositions that took place before that naming convention became common. Certainly, Philadelphians of 1876 would've found it strange usage. Is there a way the template could be modified to have a custom header option, so that historic expositions could override the behavior?
