I read that he was identified as a Used Furniture Salesman
His card said that he was a used furniture dealer.
People who have businesses. Even people who have personal businesses require themselves business cards, so that potential customers can easily contact them.
We are told in histories that Al Capone's card said he was a used furniture dealer.
The card read, "Alphonse Capone, Secondhand Furniture Dealer, 2220 South Wabash Avenue"
