The 1969 Best Dramatic Presentation Hugo was presented August 31 at St. Louiscon. Like Baycon, St. Louiscon seems to have had a schizophrenic attitude towards releasing the order of finish in the various categories. They always listed the second place finisher, but only sometimes did they list third place, and they did not rank anything that finished lower than third place.
