TULSA, OK (KWGS) - On StudioTulsa today, we welcome author and veteran magazine editor James Mauro, who drops by to tell us about his highly engrossing book, first published last year, called "Twilight at the World of Tomorrow: Genius, Madness, Murder, and the 1939 World's Fair on the Brink of War." Mauro's in-depth account of the 1939-1940 World's Fair is --- as was noted in a starred review in Kirkus --- fully seasoned "with tales of visiting presidents, kings, queens, politicians, sports heroes, and movie stars. . . . [Mauro] wonderfully elaborates on the fair's movers and shakers. . . . [This book] will likely appeal to fans of Erik Larson's 'The Devil in the White City.' . . . A delightful time capsule, skillfully unpacked."
