We point the Good Seats Wayback Machine back a hundred years to the Roaring '20s - for a look at baseball's then-New York Giants and their larger-than-life owner Charles Stoneham - with baseball biographer Rob Garratt ("Jazz Age Giant: Charles A. Stoneham and New York City Baseball in the Roaring Twenties"). 

From the dust jacket of Jazz Age Giant:

"Short, stout, and jowly, Charlie Stoneham embodied a Jazz Age stereotype—a business and sporting man by day, he led another life by night. He threw lavish parties, lived extravagantly, and was often chronicled in the city tabloids.

"Little is known about how he came to be one of the most successful investment brokers in what were known as 'bucket shops,' a highly speculative and controversial branch of Wall Street. One thing about Stoneham is clear, however: at the close of World War I he was a wealthy man, with a net worth of more than $10 million.

"This wealth made it possible for him to purchase majority control of the Giants, one of the most successful franchises in Major League Baseball. Stoneham, an owner of racehorses, a friend to local politicians and Tammany Hall, a socialite and a man well-placed in New York business and political circles, was also implicated in a number of business scandals and criminal activities.

"The Giants’ principal owner had to contend with federal indictments, civil lawsuits, hostile fellow magnates, and troubles with booze, gambling, and women. But during his sixteen-year tenure as club president, the Giants achieved more success than the club had seen under any prior regime."
