Like countless Bay Area immigrants, Jack Shelton came and then made his own way.

Born in New York in 1923, he arrived here in 1956 as a direct-mail specialist but branched off as an author five years later because "San Francisco is such a unique and wonderful city, it deserves a unique and wonderful guide book." His target audience: "the person of wide general interests, who is anxious to see new things and enjoy new experiences."
