A longtime saloonkeeper, Pfeffer operated several establishments at various times, first in Louisville and later in Chicago. The last and most famous of these, Pfeffer's Theatre Court Buffet, was located at 22 S. State Street, in back of the McVickers Theatre in downtown Chicago. Opened in 1911, it became a popular watering hole for ballplayers, actors, and other celebrities. A composite portrait of the "stonewall infield" adorned the official stationery, and Fred enjoyed a thriving business for nearly a decade. However, with the enactment of Prohibition in 1920, he was forced to sell everything for the sum of $1.50!
Think I said around 1912 to be exact.
capanson.com list it as 1920's, but as friend Mayhem Miller was quick to point out, the style of the pc seems much earlier
