"Yesterday at the Exposition [from the Times-Herald, June 27, 2090]" is an early short story by L. Frank Baum. Baum submitted his story in a contest run by The Chicago Times-Herald, for stories on the theme of "Chicago's International Exposition, A.D. 2090." The concept was that the stories were reports on an imagined World's Fair held in Chicago two hundred years in the future. Baum's story was printed in the newspaper on Sunday, 2 February 1896; it won third prize. The story was reprinted in The Baum Bugle, in 1976.
