Petaluma’s Katherine Rinehart has been spreading the word that Al Barna and Randall Ann Homan — the founders of San Francisco Neon, a nonprofit advocating for the artistic legacy of historic neon signs, and enthusiastic supporters of Rinehart’s Petaluma Signs Project — are the subjects of a recent two-episode run on the eight-year-old Bay Area podcast “Storied: San Francisco.”

In a note to supporters of the Signs Project, which is currently fundraising to restore the iconic “Baby Chicks” sign at the historic Poehlmann Hatchery building on Petaluma Boulevard, Rinehart said, “Here is a great podcast featuring our friends and partners at San Francisco Neon. So much to share. I hope you enjoy listening and learning.”

Barna and Homa are the authors of an influential book all about neon signage, “San Francisco Neon: Survivors and Lost Icons,” which is discussed in episode two of the two-part interview.

Part one of the podcast, produced and hosted by Jeff Hunt, includes the story of how the art of neon, and the neon lighted objects themselves, came to be such a significant focus of the couple’s life and careers. That story involves an iconic sign in the Mission District of San Francisco that mysteriously vanished overnight, leading Barna and Homan to investigate. Part two describes the ways in which their shared neon enthusiasm inspired them to start documenting the neon signs of the city, photographing the eye-catching lights at night across San Francisco.

Launched in 2017, “Storied: San Francisco” is described by its creators as “an audio and visual documentary about people — artists, bartenders, community leaders, doctors, lawyers, and small-business owners — and places that make this city so damn unique.”

Rinehart is the author of the book, “Petaluma Vintage Signs Guidebook,” a survey of 15 of Petaluma’s most recognizable and beloved historic signs.
