We have many, many photographs of different subjects in our collection that we can't identify. We're fairly confident they're Sonoma County shots, but beyond that...? Every so often I spot one that I do recognize and strike it from the long list, but most remain mysteries. This week's set comes from a large group of unidentified Sonoma County commercial/industrial buildings -- I think they may be located in Petaluma or nearby -- and I'm hoping someone can pin a name and location to one or more.
