Just a four-minute walk from Kansas City’s old First National Bank at Baltimore and 10th Streets —now the home of the downtown Central Library — some of the biggest names in American entertainment once made their way to a small photography studio and a man they trusted to cast them in just the right light. Al Jolson and Eddie Cantor. Fanny Brice and a local ingénue named Billie Cassin (who’d eventually become Joan Crawford).
