The 1933 World Series began on 3rd October; the 21st amendment, ending national Prohibition, was not ratified till 5th December of that year.
Sarnoff suggests that prohibition ended about midnight on Friday, April 7, 1933. "Pedestrians shouted the words 'Pros It'. Nightclubs, hotels., and restaurants were packed". From the Post, dated April 7, '33. During the celebration, a truck escorted by motorcycle cops took a shipment of beer to the White House.
"Will beer be sold at your ballpark?", FDR asked Griff and John Heydler, president of the National League.
"Griffith said beer had never been sold in the stadium and it wouldn't now. Heydler said his league would permit the operation of bars in the few stadiums that had sold beer prior to Prohibition". [Sarnoff references the Philadelphia Inquirer, Apil 7, 1933]
The two extra fans fighting, after the "war in Griffith Stadium" on April 27th, were not noted as drunk...just both named "George". Sarnoff says that the George who won the fight got arrested...one of three fans arrested for joining the battle.
[Maybe FDR anticipated repeal, or maybe the authorities quit enforcing Prohibition? I was a history major, but prohibition was not a specialty.]
