After getting word (thanks to Max for the tip) that most of the ex-Petco building had been taken down during our rainy Thursday, we went by at midday today for followup photos – and noticed the construction crew taking down a sign from the newly exposed building to the south. There’s no mistaking the old Firestone Tire logo:
Online searching yielded multiple references to 4724/4736 California SW as a Firestone store in the mid-20th century; it opened in 1946.
Since their construction crew was taking it down, we asked the 4730 California (formerly 4724) developers what happens to the sign. It belongs to the owner of the adjacent building, we’re told, but was taken down to “remove and secure it to prevent unnecessary damage or building up against it again. The ultimate disposition of the sign will be entirely up to its owner.”
