The original photo came from an eBay sale years ago, and got collected on one of those sites which scrapes old sale info from eBay in hopes of getting clicks on their ads. I don't have any details about the original beyond that, but we'll just have to be grateful the photo got saved for future sharing.
The next block closer to Castro St. also held an interesting industry: the California Supply Co.'s tomato and pickle plant. This is the second pickle plant I've encountered in the Santa Clara Valley; the other was Del Monte Plant #4, out by San Jose's Japantown. Who would have thought of the Valley as a big pickle producer?
