A friend and regular reader sent me this old photograph of the Hamm’s brewery sign at night, taken in San Francisco around 1954, the year the Hamm’s Brewery opened. It’s a nighttime shot of the iconic Hamm’s sign on the roof of the brewery that was located at 1550 Bryant Street. When it was built, “it was the largest commercial sign on the West Coast.” The brewery closed in 1972, and sign taken down three years later, in 1975. According to Wikipedia, it was a “20-by-80 foot sign, with a 3-dimensional 13-foot beer chalice on top, [and] appeared in the first Dirty Harry film. In the early 1980s, the beer vats were first squatted and then rented out to punk rock bands. Known as “The Vats,” the brewery was a center of San Francisco punk rock culture with about 200 bands using individual vats as music studios. The building was renovated in the mid 1980s and converted into offices and showroom space.” In 2012, the Chronicle did a piece about the sign’s fate, What happened to the Hamm’s Brewery sign?, that included additional photos taken during the day, but the sign looks most impressive at night, and it was even animated, with neon rings of beer turning on and off in sequence, so the glass of beer looked like it was emptying and then filling up again.
