The Haas Candy postcard depicting the Cliff House has a connection to early San Francisco radio. The card refers to “Simpy Fitts,” a comic character created and performed by Monroe R. Upton, who appeared on KFRC radio in the late 1920s. His program, called the *Seal Rock Broadcast*, was sponsored by the Haas Candy Company and featured a sea-lion sidekick named Dippy. Despite its title, the show was not actually transmitted from the Cliff House or Seal Rocks.

Haas Candy had been one of the city’s leading confectioners since the 1870s, operating from Mint Alley near the Old Mint. During Prohibition, when candy stores and soda fountains became popular social spaces, Haas used radio sponsorships to reach new audiences. The partnership with KFRC reflected a novel form of cross-promotion—pairing a local candy brand with one of the most dynamic new media of the era.

The postcard itself appears to have been part of this marketing effort, perhaps a souvenir or a “try again” message from a Haas giveaway rather than a retail advertisement. References to both Haas Candy and Simpy Fitts appear in "Broadcast Weekly" and "Radio Digest" issues from 1929 to 1931, confirming the connection. Surviving examples of these materials, along with photographs of the Haas Candy Factory and related radio ephemera, illustrate how the company blended humor, local imagery, and mass entertainment to promote its products.
