Between May and July 1914, approximately 2 million visitors attended the Bugra exhibition.
Notes on verification
Multiple independent sources (German Wikipedia, Austrian Posters, The European Spectator, DNB blog) corroborate the ~2 million visitor figure for the Bugra exhibition prior to WWI's outbreak in early August 1914, consistent with the claimed May-July timeframe.
